護理指南

TTSPORT 7642TK 重載六活塞大制動套件，適用於豐田Land Cruiser 250 Prado及雷克薩斯GX550

全新LC250和GX550設計用於實際使用——大多數車主不會將它們保持在展廳重量。

一旦加裝鋼製保險桿、滑板、底盤護板、抽屜、冰箱、車頂帳篷以及額外燃料或水，制動系統的負荷遠超原始規格所預期。7642TK前套件讓前端性能與越野實際需求相符。

LC250/GX550專用安裝： 7642TK專為250平台的前輪轂和輪轂設計，採用原廠式安裝點與一體式轉子。無需切割車架或自訂支架。
重型長途旅行用活塞尺寸： 擁有63.5平方厘米（9.84平方英寸）活塞面積的鍛造六活塞卡鉗，適用於每天承載實際旅行重量的車輛，而不僅僅是偶爾周末使用。
內部油路設計適用於崎嶇路段： 卡鉗內部設計能在長時間行駛顛簸、沖刷和緩慢技術駕駛後保持均勻壓力與踏板感受。
32毫米高碳轉子： 335 / 345毫米的轉子配備32毫米厚的波紋槽環，增加質量與散熱，滿足在高範圍下坡或載重穿越阿爾卑斯山口時的需求。

如果你的LC250或GX550是用作長途遠行而非日常通勤SUV，7642TK是能在下坡時提供額外餘裕的前制動升級方案。

是否適合？您的三步檢查

1. 輪圈直徑

確認你的LC250 Prado或GX550配備17英寸或更大尺寸的輪圈，適用於前大制動套件。

2. 輪輻間隙

測量從煞車盤安裝面到輪圈背面之間的距離。至少需要 94 毫米 (3.7 吋) 的空隙。

3. 車輛型號

驗證你的LC250或GX550年份、引擎與制動套件。如有疑問，請提供車輛識別碼（VIN）、輪圈規格與常用載重，我們將確認正確配置。

需要可列印的適配模板嗎？ 聯繫我們我們將通過電子郵件發送一份針對您的輪轂配置的1對1清關模板。

常見問題

7642TK對新款LC250或GX550來說是否過於強大？

如果車輛保持接近原廠重量，是的。7642TK針對添加裝甲、儲存空間、車頂負載和拖曳的車主設計。一旦平台用於真正的長途旅行，較重的前制動系統不再是奢侈，而是安全保障。

這會影響越野低速行駛的操控性嗎？

不會。此套件調校為在鬆散路面上平滑、可控的制動。當需要減速載重車輛時，你會感受到更大的制動力，但在緩行時的調節仍然輕鬆，這在技術性路段尤為重要。

我的本地4x4或剎車店可以安裝這套套件嗎？

可以。這是一個螺栓式系統，配有平台專用的支架和硬件。任何有能力的4x4或剎車店都可以安裝，只要他們遵循標準的大剎車程序並進行適當的排氣，使用高品質的液體。

LC250 和 GX550 7642TK 套件包含哪些內容？

您將收到一套完整的前軸組件，適用於 Land Cruiser 250 Prado 和 Lexus GX550：

2個TTSPORT 7642TK 6活塞鍛造卡鉗

Heads Up! What to Know Before You Install

You’re here because you’re passionate about your ride, and so are we. We want your TTSPORT brake upgrade to be a total win. Here’s some straight talk to make sure everything goes smoothly, from fitment to bedding in.

Our Return Policy

Look, we know you get it. Your brake kit is custom-made for your specific car. That means once it's built, it's yours. We can only accept returns if there’s a genuine quality defect from our side.

Sometimes, aftermarket wheels can be tricky. Depending on the design, you might need spacers for clearance. We’ll do our best to help you figure it out, but issues related to wheel spacers don't qualify for a return.

1. Let's Nail the Fitment

To get this right the first time, we need your help. Before you order, please give us the following info:

Your vehicle's Make, Model, Year, and VIN.
Your wheel size and specs.

We’ll likely ask you to confirm some measurements and send a few photos of your wheels. Please double-check everything you send us. TTSPORT isn't responsible for fitment issues if the specs you provided were off.

We check every single part before it leaves our shop. When your kit arrives, give it a good look-over. If you spot any potential quality issues, let us know within 24 hours.

2. The Fun Part: Bedding In Your New Brakes

This is key to awesome performance. Don't skip it.

Find a safe, open road. Bring your car up to 40 mph (approx. 65 km/h) and apply firm, steady pressure to slow down to 10 mph (approx. 15 km/h). Don't come to a complete stop. Do this 10 times to get the pads and rotors acquainted.
For the next 300-600 miles (approx. 500-1,000 km), take it easy. No crazy hard stops. This cures the pads and rotors and ensures a long, happy life.
You'll notice our high-carbon steel rotors have a colored, grooved surface. This isn't just for looks—it helps speed up the bedding-in process and fights off corrosion.

3. Our Promise: The TTSPORT Warranty

We build our kits to last, and we stand by our work. Here’s the breakdown:

Calipers: Covered for 1 year against manufacturing defects. We also offer lifetime maintenance (you just pay for parts).
Rotors & Hoses: Covered for 90 days against manufacturing defects. These are wear items, but you can expect them to last 25,000-35,000 miles (approx. 40,000-60,000 km) depending on your driving style.
Brake Pads: Covered for 90 days against manufacturing defects. Typically good for 15,000-25,000 miles (approx. 25,000-40,000 km).
Custom Hats/Brackets: We guarantee they'll fit perfectly out of the box. Once they're installed, they're not covered under warranty.

4. Pro Tips for Long-Lasting Performance

After a session of hard driving, let your brakes cool down naturally. Don't spray them with cold water—that's a fast way to warp rotors.
Brakes feel different in the rain. Give yourself some extra stopping distance.
If you hear or feel anything weird—grinding, shaking, etc.—talk to your installer right away.

Recommended Service Intervals:

Rotors: Replace them when wear exceeds 3 mm (approx. 0.12 inches).
Front Pads: Plan on swapping them every 20,000 miles (approx. 32,000 km) or so.
Rear Pads: Usually last longer, around 35,000 miles (approx. 56,000 km).
Brake Fluid: Flush and replace every 25,000 miles (approx. 40,000 km) or every 2 years, whichever comes first.
