ABS problem?

Furb · May 02, 2010, 09:33:47 PM

well, i really like the feel of it and less things that can cause problems...
i must say, that it sometimes takes a bit of skill if you combine 300hp, a wet road, a big brake kit and no ABS :lol:

i dont know how strict the MOT is in the UK, since i am in Holland.
i left the sensors in there, now i use them for my Racelogic Traction control system.
if you just take out the ECU with harness completely, the idiot lights wont even go on

okay goodo,like you say its one less thing to go wrong and when it was running it used to pull the car all over the road and nearlly put me in the armco so im all for junking it.

Well I took the car out lastnight. It seemed better. Still not quite right but it wasn\'t doing it as much. Maybe I do just have air in the system some how. Seems odd though since its been a year since I last changed the fluid. Not really sure how air got in the system. Gonna take the wheels off today and check the callipers, pads and breeak lines for clues.
Does anyone know if the idiot light would come on if the pads are low?

only if you have the sensors there which I dont think many did,if at all. The light will come on for low fluid though.
Do you have the workshop manual? it has an excellent manual for brakes. I\'ll post here if its small but otherwise send me an email and I will send you it that way.

Its nearly 3MB so just email me if you need it.

Right a bit of an update on this. The problem is still there. Although not as bad. I have changed pads for some fast road/track pads (Racing Brake). I\'ve had every calliper off and they are ok. I\'ve cleaned the toothed pick up rings with a wire brush. The fronts were fine but the rears were a bit corroded. I also checked the clearances of the sensors-toothed pick up wheel. They were all within tollerance. Three of them were 0.4mm and the drivers side rear was 0.7mm. I\'ve also been through the ABS ECU as per FSM and it checked out ok. So Im thinking its a dodgy sensor maybe.

Now the problem I have is my track day on next week. I really need to sort this asap. Whats the best line to take guys? Do I remove the ABS all together or try and fix it when I still don\'t know 100% what the problem is? How easy is it to remove the ABS and what is needed to be removed for MOT as that is due in 3 weeks too!

HELP!

do you think a new ABS ECU would sort it out - or have you tried that ?

TiddlesRX7 · June 02, 2010, 06:35:36 PM

I have checked it. I sent you a msg the other day about that one I gave you a while back.

as soon as mine gets to carls ill have a working pump and ecu if any one wants it . im removing mine for a hydrobrake . had my rex out in the snow and the abs was going mental so i know it works lol

grinder · June 03, 2010, 09:28:48 AM

yeah i got it and took it to the meet on sunday

have you tried a different ECU though ?

i have the full ABS pump in the garage if you need to test yours

TiddlesRX7 · June 03, 2010, 09:31:15 PM

Cheers Stu + Batman I may take one of you up on the offer. im thinking though if I can\'t fix it for cheap then I may just remove it altogether. Pete has sugested just pulling the fuse for now and see if the problem goes away. I\'ll try it over the weekend. If its ok I\'ll track day the car like that and then sort it out afterwards.
Thanks.

Oh Stu no I haven\'t tried another ECU. Thats why I wanted to make the meet so bad.

grinder · June 04, 2010, 09:40:38 AM

ahhhhhhhhhh , i thought you had tried an other one

just a shame you arent like 30 mins away - you could have bobbed down and we could have had a play

TiddlesRX7 · June 04, 2010, 03:20:20 PM

Im only an hour away bud;)

I was at a mates last night and when doing a 3 point turn it happened again. So parked it on a hill facing up the hill and bled the ABS unit again. Seemed to get a good spurt of air out of one of the nipples. So hopefully it was just a little airlocked. Gonna run it over the weekend and see what happens.

grinder · June 07, 2010, 01:44:38 PM

any news mate ?

TiddlesRX7 · June 07, 2010, 04:20:49 PM

Well no not really. After the last bleed it seemed alright again. Atleast for a little while then it did it again (not as bad though). So I took the ABS fuse out and have been driving like that since yesterday. Been off work today to prep the car for Cadwell on Wednesday. So been running around town in it and it seems ok without the ABS fuse for now.
Think I\'ll try bleeding it again when I get to Cadwell and see what happens.
