What vehicles does the DR4 front drift kit fit?

The DR4 is a motorsport front big brake kit that uses radial-mount calipers with vehicle-specific brackets and application-specific brake line fittings. Fitment is engineered per chassis, knuckle, hub, and wheel package. Confirm your chassis, suspension, and wheel setup with us before production so the bracket, rotor offset, and line ends are built correctly.

What rotor size does this kit use and what wheel clearance is required?

The matched engineering spec uses a Ø325 mm x 12 mm two-piece solid rotor with 4-piston forged calipers (caliper L 178 x W 82 x H 106.5 mm). Recommended minimum wheel size is 17 in. Larger rotor diameters (such as 330 x 12 mm or 343 x 11 mm steel options) are available through the build sheet; clearance must be verified with your wheel and spoke profile.

Why solid rotors and bootless racing pistons on a drift kit?

Drift use generates long, sustained front-axle braking and trail-braking inputs, but front rotors run a narrow effective duty cycle versus circuit racing. A solid Ø325 x 12 mm rotor saves rotating mass and improves steering response, while bootless racing pistons reduce seal drag and tolerate higher caliper temperatures. Both require regular inspection and competition-style service intervals.

What is the operating window of the included pad and can I change compounds?

The supplied pad runs 0–600 °C with an average friction coefficient around 0.38 on iron or steel rotors. Actual mu varies with temperature, line pressure, and rotor condition. The caliper accepts a range of motorsport pad shapes, so you can shift compound and bite characteristics for entry stability, lock-up control, or endurance heat without changing hardware.

Is bedding-in required and how should I service the kit?

Yes. A proper bed-in cycle is required to transfer pad material onto the rotor face and stabilize friction before hard use. For competition service, inspect pistons, seals, pad backing plates, rotor face wear, and braided line ends between sessions. Bootless pistons demand cleaner shop discipline than street calipers.

Can I customize caliper color, rotor size, or bracket spec?

Yes. The DR4 is built to order. Rotor sizing (325, 330, 343 mm options shown in our price sheet), bracket geometry, and brake line lengths are tailored to your build. Note: chrome finish is not available on this caliper. Send us your chassis, hub, knuckle, master cylinder, and wheel data to start a build.

常見問題

DR4 前漂移套件適用於哪些車輛？

DR4 是一款賽車用前大制動套件，採用徑向支架卡鉗，配備車輛專用支架和適用的制動管接頭。適配性根據底盤、轉向節、輪轂和輪組進行設計。請在生產前與TTSPORT確認您的底盤、懸掛和輪組配置，以確保支架、轉子偏移和管端正確製作。

此套件使用的轉子尺寸為何？需要多大的車輪間隙？

匹配的工程規格使用直徑 325 毫米 × 12 毫米的雙片式實心轉子，配備4活塞鍛造卡鉗。卡鉗尺寸為長178毫米 × 寬82毫米 × 高106.5毫米。建議的最小輪圈尺寸為17英寸。較大直徑的轉子（如330毫米 × 12毫米或343毫米 × 11毫米鋼制選項）可通過組裝單獲得；必須與您的輪圈和輻條輪廓確認間隙。

為何在漂移套件中採用實心轉子與無罩蓋賽車活塞？

漂移使用產生短促銳利的前軸制動和追跡制動輸入，但前制動盤的有效佔空比比賽道賽車更窄。實心直徑325毫米×12毫米的制動盤可減少旋轉質量並改善轉向反應，而無護罩的賽車用活塞可降低密封阻力並耐受更高的卡鉗溫度。兩者都需要定期檢查和比賽風格的維護間隔。

所附墊片的操作範圍為何？可以更換成不同的材料嗎？

提供的制動片在鐵或鋼制動盤上可在0–600°C範圍內運行，平均摩擦係數約為0.38。實際摩擦係數會根據溫度、線壓和制動盤狀況而變化。卡鉗接受多種賽車用制動片形狀，讓您可以調整配方和咬合特性，以提升入彎穩定性、鎖死控制或耐熱性能，而無需更換硬件。

需要進行磨合嗎？如何維護套件？

需要。正確的磨合程序能將墊片材料轉移到轉子表面，並穩定摩擦性能，避免硬用。在比賽使用時，建議在每場比賽間檢查活塞、密封件、墊片背板、轉子面磨損以及 braided line 結端。無罩蓋賽車活塞比街用卡鉗更需保持清潔的維修紀律。

我可以自訂卡鉗顏色、轉子尺寸或支架規格嗎？

是的。DR4是按訂單生產的。制動盤尺寸、支架幾何形狀和制動管線長度都會根據您的車輛定制。此卡鉗不提供鍍鉻表面。請提供您的底盤、輪轂、轉向節、主缸和車輪資料，以開始定制。

準備好為您的DR4漂移裝備進行規格設定了嗎？

請提供您的底盤、年份、轉向節/輪轂規格、主缸、車輪資料、轉向角套件以及預期的漂移用途。TTSPORT將在生產前確認制動盤尺寸、卡鉗顏色、制動片選擇、制動盤帽偏移、支架幾何形狀和制動管線配件。

Brake Kit Care Guide

A brake kit is not just a pair of larger calipers. Calipers, rotors, pads, hoses, brackets, rotor hats, mounting hardware, brake fluid, wheel clearance, and bedding procedure all work together as one system.

This guide explains how to confirm the right TTSPORT brake kit before ordering, what to check before installation, and how to care for the system after installation.

1. Before Ordering: Confirm the Full Vehicle Setup

Do not order a brake kit by vehicle name alone. The correct kit depends on the vehicle, axle position, wheel package, driving use, and brake system layout.

Vehicle year, make, model, trim, market version, and chassis code if available
Front or rear axle position
Current brake rotor diameter, thickness, and caliper type if known
Wheel diameter, width, offset, spoke shape, and inner barrel clearance
Tire size and vehicle weight changes from armor, cargo, towing equipment, or track setup
Driving use: daily street, towing, mountain driving, off-road, HPDE, rally, drift, track, or competition
Whether the vehicle uses electronic parking brake, brake pad wear sensors, ABS / ESC systems, or special hydraulic routing

Brake kits are application-specific. A visually similar kit can still have the wrong rotor offset, bracket geometry, hose fitting, caliper position, or wheel clearance requirement.

2. Understand What Type of Brake Kit You Are Ordering

Different TTSPORT brake kit series use different hardware layouts. Always confirm what the kit includes before purchase.

Direct-Mount Kits

Use direct-mount calipers and one-piece rotors where specified. These kits do not use rotor hats or caliper brackets unless the final product page clearly states otherwise.

Two-Piece Rotor Kits

Use separate friction rings and rotor hats. Hat offset, ring bolt pattern, hardware style, and rotor direction must be matched correctly.

Racing / Custom Kits

May require bespoke brackets, rotor hats, brake lines, and engineering confirmation based on knuckle, hub, wheel, and competition use.

Off-Road / Heavy Vehicle Kits

Require extra attention to wheel clearance, tire size, vehicle load, descent control, hose routing, and dust / water exposure.

Do not assume every brake kit includes the same parts. Package contents vary by product series, vehicle application, and final order configuration.

3. Confirm the Kit Specification Before Payment

Before finalizing the order, review the kit specification carefully. Confirm the brake kit is matched to your vehicle and wheel setup, not only to the model name.

Confirm vehicle application and axle position
Confirm caliper model, piston count, and caliper color if applicable
Confirm rotor diameter, rotor thickness, rotor construction, and left / right direction if applicable
Confirm brake pad compound and intended use
Confirm brake hose fitting type and routing compatibility
Confirm whether caliper brackets, rotor hats, mounting hardware, wear sensors, or brake fluid are included
Confirm minimum wheel diameter and spoke clearance requirement
Confirm lead time, shipping method, and final invoice details

If any part is not listed in the final order or product page, do not assume it is included.

4. Before Installation: Inspect the Complete Kit

Inspect every component before installation. Do not modify, grind, drill, stretch, force, or space brake kit components to make them fit.

Check all received parts against the order confirmation
Inspect calipers, rotors, brackets, hats, hoses, pads, and hardware for shipping damage
Confirm left / right caliper and rotor orientation where applicable
Confirm rotor size, pad shape, hose fittings, bracket layout, and hardware style before installation
Clean all mounting faces before assembly
Confirm torque values, bedding procedure, fluid type, and bleeding procedure before starting work
Use a qualified brake technician for installation

Safety: Brake kits affect braking force, hydraulic sealing, heat control, wheel clearance, and vehicle stability. Do not install the kit if fitment, torque, direction, clearance, or compatibility is unclear.

5. Installation Checks

Correct installation is as important as the brake kit itself. A properly engineered kit can still perform poorly if installed with dirty mounting faces, incorrect torque, poor hose routing, or trapped air in the hydraulic system.

Caliper Position

Verify caliper centering over the rotor and confirm even pad sweep across the friction surface.

Rotor Orientation

Confirm left / right rotor direction if the rotor uses directional vanes or directional face pattern.

Brake Hose Routing

Check brake hose length and routing at full steering lock and full suspension travel. No twisting, rubbing, stretching, or kinking.

Wheel Clearance

Check caliper-to-spoke and caliper-to-barrel clearance before road use. Wheel diameter alone is not enough.

Brake Fluid & Bleeding

Use the correct brake fluid type and bleed the system until pedal feel is firm and consistent.

Hardware Security

Torque all brake hardware to the specified value. Do not reuse damaged, unknown, stretched, or corroded safety-critical fasteners.

6. Bedding and First Heat Cycle

Brake pads and rotors need a controlled bedding process before full performance is available. Bedding helps create an even transfer layer on the rotor surface, improving bite, pedal consistency, and vibration resistance.

Follow the bedding procedure supplied with the exact pad and rotor compound
Use moderate heat first unless the supplied procedure requires otherwise
Do not start with emergency stops on a fresh pad / rotor setup
Avoid holding the brake pedal while stopped on very hot pads and rotors
Allow the brakes to cool after bedding
After the first heat cycle, inspect pad contact, rotor surface, hose routing, hardware security, and fluid leaks

Street pads, race pads, iron rotors, two-piece rotors, and carbon ceramic rotors may require different bedding procedures. Use the procedure supplied with the specific kit.

7. Initial Break-In Period

After installation and bedding, give the system a short break-in period before aggressive use. Pedal feel, pad contact, dust output, and noise may continue to settle after the first drives.

Avoid repeated emergency stops unless required for safety
Avoid hard track use until bedding and inspection are complete
Monitor pedal feel, vibration, noise, smell, and rotor surface appearance
Recheck for fluid leaks after the first road test
Recheck torque where the kit instructions require post-heat-cycle inspection
Contact TTSPORT if brake feel changes suddenly after installation

8. Routine Care and Inspection

Brake kits need regular inspection, especially after track use, off-road use, towing, mountain driving, winter salt exposure, or any brake service.

Inspect brake pads for uneven wear, taper, glazing, cracking, or backing-plate damage
Inspect rotors for cracks, heavy scoring, hot spots, minimum thickness, and runout
Inspect calipers for fluid seepage, piston movement, dust boot damage, and uneven pad retraction
Inspect brake hoses for rubbing, cuts, swelling, leaks, and fitting corrosion
Inspect brackets, rotor hats, and mounting hardware for cracks, fretting, corrosion, or loosening
Check brake fluid level, color, service age, and boiling-point suitability for your driving use
Clean brake dust from wheels and calipers regularly, especially after wet, salty, or track conditions

9. Care by Use Case

Daily Street

Inspect pads, rotors, fluid level, and hose condition during normal service intervals. Prioritize quiet operation, smooth pedal feel, and even wear.

Towing & Mountain Roads

Check pad thickness, rotor surface condition, and fluid condition more often. Long descents create sustained heat even without track use.

Off-Road

Inspect for mud, sand, stone impact, hose abrasion, dust boot damage, and caliper contamination after trail use.

Track / HPDE

Inspect pads, rotors, fluid, and hardware before and after every event. Track heat shortens service intervals.

Drift / Competition

Check rear brake temperature, hydraulic handbrake behavior, pad wear, rotor cracking, and hardware condition frequently.

Carbon Ceramic

Use only compatible pads and approved bedding procedures. Inspect rotor surface condition carefully and avoid incompatible friction materials.

10. Stop Driving If You Notice These Symptoms

Do not continue driving if the brake system shows any of the following symptoms. Inspect the system or contact a qualified brake technician before using the vehicle again.

Soft pedal, sinking pedal, or sudden increase in pedal travel
Brake fluid leak or wetness near a line, caliper, fitting, or master cylinder
Grinding, scraping, severe vibration, or heavy brake judder
Vehicle pulling strongly to one side under braking
Burning smell after light driving
Loose wheel, rotor, caliper, bracket, or hardware noise
Brake warning light, ABS warning light, or traction-control fault after brake work

Need help confirming brake kit setup or care?

Send your vehicle details, brake kit series, wheel specs, driving use, photos, and any symptoms you notice. TTSPORT will help confirm fitment, installation checks, and the correct care path for your brake kit.
