I am re-tubing the brakes on a 57 Chevy truck. It has discs (11") front and back (single piston)with a new dual master cylinder. There seems to be all sorts of components and tubing diagrams out there for the set-up I have. There are adjustable proportioning valves, residual valves, automatic proportioning valves in most of the systems I have seen.There must be someone who has done pretty much the same install and has something that works well. Any information regarding parts used would be appreciated.

there is NO easy answer for what you are looking for as you have NOT mentioned what size a bunch of the components are...   other than the rotor size...

front caliper bore size..

caliper bore sizes are very important to have close to a perfect ratio..  usually 66% on the front to 33% on the rear...  this is with even size tires... since various sizes of brake calipers are usually not available...  get this correct and you should have a decent stopping system...

there are multiple  valve combos...

pressure differential safety switch is usually one of the items.. so if one side fails. the shuttle valve goes across and shuts off the low pressure side... also turning on the BRAKE FAILURE Warning light..

proportioning valves  limit the actuation of usually the rear brakes...   increases the amount of pressure needed to overcome the prop valve before the rears can be applied...
this puts more braking on the front wheels.. reduces rear wheel lock up where there is TOO MUCH REAR BRAKE BIAS...

there are just SO MANY things to calculate  ..

you might actually want to invest in a set of pressure gauges that screw into the bleeder screw holes...

something like this... similar sets are available from multiple suppliers..

this is used to test that you have enough brake hydraulic pressure to operate the braking system...

Thanks for the info. I spoke to one of the guys at the local brake shop and he basically gave me the same things to look out for as you mentioned. Thanks again.

there are around 40 magazines on this site...

some of them have well written articles on brake bias...


there is a LOT to learn..

these are just for info... learning.. there are more... still looking for the perfect article that will explain it...
