The kit I ordered is a GM dual resevoir master with a 7" booster attached, it came with a heavy steel bracket to push the whole assembly away from the framerail (room for the booster) and a linkage offset rod to connect to the stock pedal. I believe it was made by
MP , but I can't remember which vendor took my money. The installation instructions and receipts were lost in a move a couple years ago.
For a halfton pickup, you don't really need a booster; I went with one because of the weight of a loaded panel truck. This put the resevoir next to the transmission cover, and the M/C fill hole in the floor is now useless. You can sidestep this issue with a remote resevoir on the firewall or perhaps the non-booster duals line up better with the stock floor hole. :confused:
When you go to a dual-circuit master, you must bend new line. The original configuration has three wheels on one line and the left front on it's own feed; you will never get balanced braking unless you put the fronts on one line, and the rears on the other. I spent a day under the truck with a tapemeasure, then went to NAPA for various lengths of line with flares and fittings attached. Taking my time and doublechecking each fitting, the whole brake system took a day to install.
The new M/C had 3-lb. residual pressure valves built in, but for drum brakes you will want 10-lb. valves (MP sells them for $26/each). This will take the "mush" out of the pedal and give you a quicker brake response.
Now I just need to figure out how to keep RAV4's off the grille. :rolleyes:
