Front disk brake master cylinder
Posted by: gnrand ()

I am adding the Stinger conversion kit and I am using a Chevy C10 master cylinder that was recommended in the kit. The master has a small chamber closest to the firewall and a much larger 2nd chamber. Should the larger 2nd chamber be tied into the front brakes?
Thanks
Jeff

The larger fluid reservoir is because disc brakes require more fluid since the calipers expand further as the pads wear thinner. When installing new pads you sometimes have to remove some fluid from the reservoir so it doesn't overflow when you push the caliper back in.

If the master cylinder has different size bores for the front and rear that might take some figuring. In S-10 the rear brakes hardly do anything as there's no weight back there. In a LM Corvair, the stock rear brakes are bigger than the fronts. I had an Astro Van that never needed rear brake shoes in 185,000 miles.

I'm afraid I have more questions than answers.

As a side note, the method I use when doing this is to open the bleeder screw when collapsing a wheel cyl. or caliper. Saves pushing any possible junk back up through the system. This is especially true on the modern ABS systems.
