Introduction
This document outlines considerations and experiences shared regarding aftermarket brake rotors, specifically drilled/slotted rotors, for the Toyota Prado 120 series.
Problem
Standard brake rotors on the Prado 120 may be prone to warping and shuddering under heavy use, such as frequent descents on steep grades. Heat buildup and rapid cooling can contribute to this issue.
Solution
Upgrading to slotted or slotted/dimpled rotors can improve braking performance and reduce the likelihood of warping in demanding conditions.
Relevant Parts & Brands
- DBA Rotors: A well-regarded brand. T2 and T3 series are mentioned.
- T2 Rotors: Feature bi-symmetrical curve slots for vibration dampening, even pad wear, and minimizing pad glazing. Non-directional design.
- T3 Rotors: Offer additional benefits over T2 rotors, including XG150 high carbon alloyed iron for increased thermal capacity and a tri-symmetrical slot design for improved vibration dampening and brake recovery after water crossings. TSP (Thermal Stability Profiling) is applied to HEAVY DUTY, T3 4X4 and CLUBSPEC rotors.
- RDA Rotors: Slotted & dimpled RDA rotors reported to perform well in preventing warping.
- Repco Rotors: A cheaper option that users have found success with.
- Bendix Brake Pads: Bendix 4WD pads are a popular choice. There appears to be very little difference between the 4x4 and HD versions.
- TRW Rotors: A reasonably priced brand, available from Repco.
Notes
- Slotted rotors may cause brake pads to wear more quickly (approximately 20% faster in some cases).
- Regular brake fluid flushes (every 2 years) are recommended for optimal braking performance.
