Hi All,
I have a FJ75 with a 3B in it I'm trying to get up and running, and I'm having some issues with the brakes. Symptoms - very squishy pedal, but full braking power at end of stroke - pretty unnerving driving it. If I pump the brakes I loose all vacuum assisted braking and loose all power brakes. New parts:
- Brake booster
- Brake master cylinder
- Front calipers, pads and rotors
- Rear drums, wheel cylinders and shoes - adjusted properly
I'm thinking there's something wrong with the vacuum system. The pump on the back of the alternator seems to be working because when I pull the rubber line off (I pulled it off the brake booster on the other side) there seems to be good vacuum - it sucks my thumb good. However, I don't see any sort of vacuum storage canister in the system.
The PO swapped the 3B into this Troopy allegedly from a BJ60.
Is there supposed to be a vacuum canister to store vacuum? It seems like there's not enough vacuum for the booster - either a bad vacuum pump or no storage canister to store vacuum?
