Hi, anyone had any experience with the ABS electric brake booster kit ? Good / bad or ??? I have a friend with a 35 Chevy pickup, GM front calipers, F100 rear drums, 8" dual diaphram booster under the floor, 1" bore master cylinder and the thing just wont stop ! Engine is a blown SBC. Booster and mc been checked and tested ok, pedal ratio appears ok (6.5 @ 1 or thereabouts) according to the brake guys its developing 17 psi vacuum so shouldnt require a vac tank. New caliper kits, new wheel cylinders.......still wont stop.....now looking at these electric boosters......any ideas anyone ???? Cheers guys thanks
I don't know about the ABS, but I had this problem on an off topic truck and a '32 roadster for a friend. Turned out to be the proportioning valve stuck, so he only had rear brakes.
Installed one in my pick-up about 10,000 miles ago and haven't had any problems, braking is excellent and balanced ! Expensive but I wanted a clean firewall. Highly recommend. .
I put one in a F 100 for a customer. Worked fine. You might try a smaller diameter master cylinder first.
