Triumph Bonneville, T100, T120 & Bobber Brake Caliper Rebuild Kit

Restore smooth, reliable braking performance with this TRK front brake caliper rebuild kit for Triumph Bonneville models. Replacing the original plated brake pistons with TRK stainless steel pistons provides a permanent upgrade that helps eliminate one of the most common causes of sticking calipers. Over time, OE pistons can become corroded and pitted through exposure to moisture, road salt and general wear, leading to brake drag, uneven pad wear and reduced braking performance. Precision manufactured as direct replacements for Triumph OE part numbers T2020050 and T2020542, TRK stainless steel pistons offer outstanding corrosion resistance and help keep your front brake calipers operating smoothly for years to come.

Supplied as a complete front brake caliper piston and seal kit, this is an ideal solution whether you're carrying out routine maintenance or restoring an older Bonneville. Unlike standard plated pistons, TRK stainless steel pistons are designed to resist future corrosion, making them a genuine long-term upgrade rather than simply a replacement part. Every TRK stainless steel brake piston is backed by a lifetime guarantee, while the complete kit offers exceptional value compared with genuine Triumph components. For best results, thoroughly clean the caliper seal grooves before installation to remove corrosion and debris, allowing the new seals to seat correctly and ensuring smooth piston movement.
