Upgraded front brake kit with Wilwood calipers

Fits Triumph TR4 from CT4690 (wire) or CT4388 (disc), TR4A, TR250 and TR6

Sold as a kit including brake rotors.  Brake pads are sold separately.


This Good Parts Front brake kit uses Wilwood four piston calipers with 1.62” pistons and Wilwood 11” rotors to increase the braking performance over original brakes.

  • Uses Wilwood 11″ x 0.81″ internally vented two-piece rotors.
  • Costumers can choose ULHP smooth rotors, SRP drilled and slotted rotors or GT72 Spec37 rotors.
  • Bolts on easily to original mounting bracket and fits with original dust shield.
  • Fits with stock steel or wire wheels, and most aftermarket alloy wheels.
  • Each caliper weighs only 4.9 lbs compared to the stock caliper at 9.6 lbs.  The ULHP or SRP rotor with mounting hat is 1.2 lbs lighter than the stock rotor.  Un-sprung weight is reduced by a total of 5.9 lbs per side.
  • Available in standard silver/gray hard anodized finish and red or black powder coated finish.
  • Calipers use Wilwood’s extra thick pads with 40% more wear life.
  • Brake pads are not included with the brake kit and must be purchased separately.  Customers can order the compound that best fits their intended use.

    I combined this with the rear disc conversion kit, a Wilwood pedal assembly and individual master cylinders for our ‘74 TVR. The fit is excellent, installation was easy. I inspected everything today after two years of use, all parts are perfect. What a huge improvement in brake performance.
