I run a 78 camaro with stock disk/drum brakes setup. it appears that the front brakes come in a lot sooner than the rears and I have to get the rear shoes pretty tight to get them to perform. Is this a common problem and is there a way to fix it. Is there another master cylinder that might be better than the stock one it came with.

If you are refering to the funny looking block between the MC and the brake lines the the answer is no I have not taken it out.

take her out the way i understand it that thing doesn't let pressure to the rears untill there is a certin amount being applied to the fronts first got to keep in mined thats designed for the street where you want the front to do the majority of your braking

proportioning valve is for safety it has a cylinder in it, that will shut of either the front or the rear if theres a leak.

in order to bleed brakes with the prop valve in there you need to bleed it, and or reset a button thats on the end usually.

you can use a in line bias to reduce front brake tiltons go down to 35 percent while wilwoods only goes to 45 percent or so.

drums take longer to come in naturally, they have slop in them that needs to be taken up, where the discs are ready at will, and very close to tight allready.

either way everyone should be canning the proportioning valve, you can gut it or get some fittings to replace it.
