Q & A

What's in the Box

Just what's needed to update your classic Tri-Five Chevy! Eliminate those archaic ball bearings and gain first class stopping power all at once with this front disc brake conversion kit. Rotors and caliper brackets bolt onto your original spindles with no modification or machining required. Calipers mount to the front of the spindle.

This disc brake kit will increase the total front track width by 1-3/4" (7/8” per side).

  • Uses 11" rotors and 1969-72 GM calipers (7/16"-20 inlets)
  • May not clear some 14" wheels
  • Bolts onto stock '55-'57 spindles with no machine work
  • Includes rubber brake hoses

Notes

  1. This kit will not work with the original '55-'64 Chevy 4-wheel drum brake master cylinder. It does not have the capacity to supply the proper amount of pressure for front disc brakes. For best results, we recommend using master cylinder booster kit 910-31974 (disc/drum) or 910-35557 (disc/disc) with this front disc brake conversion.
  2. Front drum-to-disc brake conversions also require a proportioning valve to be installed in the rear brake line circuit. The proportioning valve modulates pressure to the rear brakes which is necessary to prevent the rear brakes from locking up in an emergency stop situatiuon. Recommended master cylinder booster kits 910-31974 and 910-35557 incude an adjustable proportioning valve to allow for a proper installation of front disc brakes.
  3. Some grinding to the steering arms may be required to achieve full turning radius.

1958-64 Chevy Full-size Car Brake Booster Combo, Disc/Disc, Drum/Drum
SKU-91031974
                        

When you put modern disc brakes on your 1958-1964 Chevy full-size car (Bel-Air, Biscayne, Impala, 150 Series, 210 Series), you should update the master cylinder as well. Stock 4-wheel drum master cylinders do not have the capacity to supply the proper amount of pressure for disc brakes. For best results, we recommend using this simple, bolt-on master cylinder booster kit on all 4-wheel disc brake conversions or as a power brake upgrade for 4-wheel drum brake applications.

  • 8" dual diaphragm booster
  • 1" bore master cylinder
  • Adjustable proportioning valve for rear brake line
  • Master cylinder has outlets on both sides for ease of plumbing
  • 1/2"-20 and 9/16"-18 outlets

Wilwood 120-10937 D52 Dual Piston Floater Caliper, 2 Piston/1.04 Disc
SKU-83512010937
                        The D52 caliper is a direct bolt-on 2 piston replacement for the factory original single calipers on many 1968-96 GM Passenger Vehicles and Trucks. Forged billet aluminum bodies, stainless steel pistons, and competition style high-temperature seals put and end to the rust, bore pitting, and seal failures that plague the OE caliper design. D52 calipers provide low-maintenance performance and a huge weight savings with high temperature reliability for the street and track. D52 calipers mount in the stock location over stock rotors, use the original style OE D52 brake pads and an OE 7/16-20 banjo bolt brake line. Calipers can be used with most wheels that clear the OE calipers. The front calipers with 2.00 piston provide 6.28 cubic inches of piston area per caliper, to maintain the original front to rear brake bias and use of the OE master cylinder. D52 Calipers come hardened slide pins.
