Info

An economical, lightweight brake kit for 1949-54 Chevy car spindles. Your stock Chevy spindles must be machined, or use Speedway '49-'54 Chevy-style spindles. This kit uses 9-1/4" Mustang II vented rotors with common GM metric calipers.

  • Typically used on Model T and Model A to 1936 Ford front ends 
  • For use on street rod tube front axles when using 1949-54 Chevy style spindles  
  • Will not work with stock 1949-54 steering arms 
  • Not to be installed on stock 1949-54 Chevy vehicle front ends

910-31955 Instructions (PDF)

Notes

  1. Clearance between king pin axle boss and caliper bracket must be checked upon installation. If interference is found, the edge of the bracket will need to be clearanced/machined to allow for sufficient clearance though the complete turning radius.
Some parts are not legal for use in California or other states with similar laws/regulations
