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.


Includes Wilwood four piston calipers with 1.62″ pistons in your choice of standard hard anodized, red powder coated or black powder coated finish, your choice of Wilwood 11″ x .81″ ULHP smooth rotors, SRP drilled and slotted or GT72 Spec37 rotors, rotor mounting hats, hardware and braided stainless steel flex-lines to connect from the hard line on the frame to the caliper. Bolts on easily to original mounting bracket and fits with original dust shield. Fits with stock TR6 steel wheels, alloys or wire wheels. Each caliper weighs only 4.9 lbs compared to the stock caliper at 9.6 lbs. Also the hat and ULHP or SRP rotor is 1.2 lbs lighter than the stock rotor. This reduces un-sprung weight by a total of 5.9 lbs per side.  GT72 Spec37 rotors with mounting hats are about the same weight as the OE rotor.

The calipers included in Good Parts front brake kits use Wilwood’s extra thick pads with 40% more wear life. Brake pads are not included with the brake kit since there are various compounds to select for your 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.
