Title: BRAKE PROBS
Post by: andyhubbard on August 04, 2006, 20:18:12

Hi guys,when i switch on the ignition i am getting a noise from the o/s/f wing,on looking under the bonnet it's coming from a unit that i can only describe as some sort of compressor.I am also getting a lot of brake judder when pressing the brakes sometimes.Any help would be appreciated,thanks.
Having done some research i now panic as i think it's the ABS pump and i don't like the price of them.

yup sounds like abs.

could be a cheap fix like a sensor moved out of postion fooling the system into thinking a wheel has locked hence the pulsing under braking.

How hard are you braking?

The ABS should be OK as Rich has just MOT'ed that car.  The ABS pump does make a noise, don't worry, all it's doing is keeping up with the fluid drain through the ABS valve block, it's a very different system from the Disco ABS but it was working ok when I last saw it.  Does the ABS light stay on on the dash?

Hi Andy-no light on the dash,just a lot of noise from the ABS pump but the scary bit is the effect on the pedal when applied,you can feel it pulsating through the pedal and a lack of braking?.Andy.

i think my bro had the same problem with his TD5 when he first had it.
Landrove did the repair at his houise and said it was air in the system.

I check with him later but i am sure,that was what he was told.

rangie ABS is an [!Expletive Deleted!] to bleed,changed the block on a classic a few weeks ago & it took longer to bleed it than to actually swap it over

Andy, give me a ring and I'll tell you how to interogate the ABS system for recorded faults.

When you switch the ignition on how long should the pump run??

Mine runs approx 45 seconds!!

Daz800-thanks for the tip off and it was air in the system.
Garth-not sure,i'll time it and let you know.

OK, i put my hands up and i'm thick.Had a chat with RRBlues and i told him that i'd fitted a new caliper and had bled the two bleed nipples, and commented that all the ones i'd done in the past had only one.
RRB says only two what about the third,a third i say,yes he says-the one near the top on the inside. Need i say more-a small amount of air came out of that nipple and hey presto,problem solved.

Andy,

Landy Manual for ABS RRC (94 model group) states the need to bleed the pump and ABS block as well. You may have got away with it on this occasion by the souinds of it but if needs be I can mail you the necessary prtocess... and to echo another poster in here.... it is a [not very nice job]to do. not difficult.. just time consuming.

Kindest
