Does anyone have instructions on how to rebuild master cylinder on 1957 Chevy 3100? I just bought a rebuild kit. Doesn't look complicated but there always seems to be a trick or two that if you know will make it a lot easier. Appreciate any help you can give. Pretty sure this is the problem. Replace brake shoes/wheel cylinder kits front and back on my 3100 57 truck and the pedal has to be pumped to get a good brake, but if you continue to hold it it will finally go to the floor..feels like it is leaking by the seal(it makes driving an adventure

)
thanks
