Q: My 1953 Chevy 1/2 ton truck project has hit a snag. I recently installed a 283 small block, modified pedals, and a master cylinder from a 1960s Chevy truck. Somehow it has all added up to poor braking power. It takes a lot of pedal pressure to stop and the fade is terrible. What do you think caused this problem and how can I fix it so I can stop on a dime?
A: If you’ve changed the angle from your foot to the master cylinder or moved the master cylinder rod, then it can cause poor braking. You should also inspect your pedals. An irregular bend can increase the pedal pressure needed to stop. If you still can’t diagnose the problem, then step up to a larger master cylinder bore size (we recently covered bore size in this article). A new set of brake drums and metallic shoes will also improve braking power, but you’ll still experience fade. For true “stop on a dime” performance, upgrade to power disc brakes with a conversion kit from SSBC. It’ll give your classic Chevy 1/2 ton modern day stopping power.
