Intermittent buzzing sound from ABS pump :-(

Post by catgroom » Tue Jul 25, 2006 8:47 pm

Hi!

I have an intermittent,but regular,buzzing coming from the ABS pump/accumulator if I have the key turned to the first click.This is with the engine off obviously.

When I drive it along,the ABS relay clicks all the time which is really bloody annoying!Why?????

Also,when I hit the brake pedal after not doing so for a little while,the ABS light somes on,immediately followed by the red handbrake warning light!

Im lost,ABS doesnt pulse properly either.

Poxy bloody thing! :cryhard:

OK OK,man I cant handle so many responses in so short a time.Gods sake,do hold back!!!!

Now then,it appeared that the ABS pump and accumulator needed changing.

The seals are simply gone in the pumpus!Mmmmmmnnnnnneeeeerrrrrr!Bugger!

Dont know about noises when driving but the accumulator will buzz now and then when you turn the ignition because it needs to draw brake fluid into the pump.

Thx for that Rob!
Alas the seals are gone,so that the pumps constantly leaking past its seals and the accumulaotrs constantly attempting to refill!

I have located a free one,thanks to the forum once again.

Id also like to thank my family,my producer,my sponsors,Volvo,Brascos bastard ball joint,his Mum,the dog and Alan Partridge

Just to let you all know that it was NOT the cylinder at fault.

This is a 92 car with the older type ABS naturally.The MAX mark was nowhere near MAX enough fluid for this car.It does state fill to max and check level with a charged accumulator.Sure,but it still wasnt enough.

It was suggested to me recently by Rich that he was sure that some of the cars of this age he'd seen had reservoirs filled higher than the MAX.

This has eliminated the problem of flashing brake/ABS lights,and annoying clicking relay!ALso after a good bleed it stops on a milk bottle top!
