What's the bore on those wheel cylinders? I'd be surprised if it's the same as ours. Your rear brakes might lock up without much effort.

 

Well i finally fixed my rear brakes and it made a world of difference. They were shot and way out of adjustment. New slaves, shoes, auto tension kits and hub seals. Oh yea and all new ebrake cables its soooo nice to finally have a good ebrake!

 

Originals are 1". The Chevys are 11/8". I am replacing master cylinder now, it had a very long pedal. I did push it hard and no lock ups, they could stil need tighter adjustment and I will as they get settle in.

Happy so far
