Hi all, in a tandem split brake system(front/rear brakes) does the piston closest to the firewall control the rear brakes or the front brakes??
On my Suburban it is for the front. But I'm not sure that all cars would be the same. If one resevior is larger it is for the front as they will do most of the work even with 4 wheel discs. Why do you want to know? - Bill
More or less put together a Lincoln Continental Signature Series that had power brakes with a pump rather than a booster, I think the pumps after stopping to work, the guy I'm doing it for has a donor car with a brake booster and master cylinder instead of the pump, going to swap it too the other car. He said he looked at the master cylinder and said the resevior compartments are the same size, didn't wanna hook it up wrong and not be able to supply enough fluid to the front or rear brakes. I'll get the info from Mitchell On Demand from the shop in our area Monday but thtanks for all the help.
4 wheel disc cars with have 2 reservoirs the same size. Dic/ drum cars will have a smaller one for the drums [needs less fluid to move the cylinders]. If it's on the car uggest you trace the lines and see where they go! - or check the manual for the car it came off
