Brake problem

After having the boring feeling with my Esprit yesterday - decided I'd better take it for a good spin. On my arrival home just as I turned into the drive, the brake warning light came on and wouldn't go off, at the same time there is no power in the pedal and brakes. So what's up???

That will teach me not to get ratty about the Esprit - it must have heard me. I hope it's not anything terrible like master cylinder stuff?

well according to Geoff at E&E he thinks it something to do with the vaccum pump/servo it either needs a new unit or one of the pipes have come off.

Hi Geoff,

Im interested to see how you get on with this. My S4 has an abs light issue and Im concerned it could get as bad as yours. Basically, go for a good run out with sustained driving. Lots of excessive breaking is not necessary. After a while of continous driving, approx a good hour or so my ABS warning light will come on and remain lit. I dont notice any difference in breaking performance when abs warning light comes on. My S4 just missed out factory Brembo's and I've always thought my breaks where crap they just remain crap when abs comes on. However if I stop, switch off and then restart normally the ABS light doesnt stay lit.

Good luck getting yours sorted!

Keep the faith. :huh:

I doubt it's related - the SE 89' doesn't have ABS. Before this my brakes were excellent, this happened very suddenly, thank God, just outside my drive. I had the car up on the axle stands this evening and checked the pipe work which seemed fine. But after running the engine and detatching the vaccum pipe from the brake fluid resevoir I found that there is no vaccum, so it's most probably the brake servo pump. It seems to involved for me to change it so I'll have to get the car to a mechanic. The other thing I did notice was that there was a lot of sticky/oily fluid underneath the pump area which could point to it being knackered. Thanks for your interest.

Geoff.

sounds like you have found the problemo there Geoff. just before i bought mine, matey had a knew vac pump fitted too, at about 52000 miles IIRC, so they are a source of grief it seems. there will be some engine/heater related problems too, as the vaccum seems to work other things as well.

Thanks for that. I spoke to Geoff at E&E again this morning, and he's not convinced that it's the vac pump, as in all the years he's only changed 2, so he thinks it 's rare. He told me to keep looking for a vac pipe off, using the manual to find all the possibilities. So that's what I'll have to do.

Are you sure it has an input in the heating?

I had the vaccum pump literally fall off a couple of years ago ...exact same symptoms...you're in the right spot.

Thanks all - I've studied the manual more closely and it does seem that in the Turbo versions, the vac pipe for the brake servo unit is linked to the heating. I'll have to try it out tommorow.
