power brake conversion ??? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

i just converted to power brakes on my 71 c10. the brakes are super touchy. the lock up real easy. i made an ajustable push rod, so im pretty sure thats not the problem. the booster is also brand new. its off a 71 3/4 ton. dont know if that matters.

any input would be great thanks!!!

Did you add a power booster only?
Did you add disc brakes?
Did you use the correct proportion valve?
Did you change master cylinders?
Correct master cylinder? (drum/drum or drum/disc)
Which wheel(s) lock up?

factory disc/drum. only added the booster. and never opened the hyd. so no need to bleed. the rears are looking up with minimal pressure on the pedal.

Mine was the same way, just needed to get used to having good brakes. Those 3/4 tone set ups have a lot of braking power.

get a proportioning valve better yet get an ajustible one then you can play with your front to back power ratio there only $40 through summit

well come to find out the rear shoes were adjusted WAY to tight. i backed them off and it stops way smoother haha. guess you should go over things like that when u buy a truck. anyways thanks for the input fellas.
