Rock hard brake pedal !!!

Post by dirtydirtydiesel » Wed Nov 29, 2017 11:59 pm

As the title state's
Jumped in the old girl tonight after work, drove across the car park put my foot on the brakes :shock:
W.T.F rock hard brake pedal & no brakes :shock: , managed to get her to stop ( luckily I wasn't going very fast)
Pressed the brake pedal really hard & it worked :roll:
Pumped them a few time's before driving home very gingerly :?
I have no faith in them now, Anyone got any ideas / heard of this before

All advice appreciated, many thanks DDD.

Same problem as this one?
Or would have except the pedal didn't move! Luckily I was going slowly and the handbrake managed to bring it to a halt. Moved off, very slowly and applied brakes again, pedal went down but I could feel it grinding a bit through the pedal. Managed to limp it home through the quiet backstreets and have left it there since, it was just downright bloody dangerous!

Yes sounds as though have no vacuum, the brakes aren't very good without it :shock: Either the vacuum pump as mentioned or the brake servo or a vacuum leak somewhere. If its an Hdi there won't be much turbo boost either, just changed mine for that reason and it improved the brakes as well. Check the solenoids on the bulkhead behind the top of the engine for leaking rubber pipes.
