P38A ABS Fault on Dash, Nothing on Nanocom?

Certainly when I've left it overnight, I've not timed exactly how long it takes to drain
It's always been on the fourth press from day one though

Well, you know what these old girls are like, there's not one the same as another

@kermit_rr you should be fine if it kicks in every fourth pump.

It can take lil bit get up to pressure first thing after standing.

Turn off ign, pump brake pedal several times to diminish any stored pressure, then switch ign on. The pump should run for approx 10 seconds. Any longer and your accumulator sphere has lost it's ability to store pressure. Press the brake pedal and let go, does the pump start immediately? If so, again, the sphere is knackered.

No need to reduce pressure to test, just count the number of times the brake pedal can be pressed before the pump runs. First run of the day is about 30 seconds and then about 10 seconds every 5th or more brake pedal operations.

New accumulator on order.
Mine takes about a minute to get up to pressure then runs every press

How much was it? I would have tried a bleed just incase.

£114.95 for a genuine Wabco one from Fleabay.
It’s been like it since I got car and long before I adjusted the brake fluid, so it needs changing anyway.

RangeRoller dt · Jul 6, 2019

That’s not bad. Stc2784 (just bulb and o-ring) is £90 +vat.
Whole unit reconned is about £1G I think.

£108 from Island 4x4.
Before changing the accumulator be sure to de-pressurise the system according to the book.

£108 + VAt. I looked their earlier

Including VAT, I have just bought one.

Sorry, I stand corrected. Sure I look there, but hey ho, too late now, one less pint for me tonight then

Well whaddaya know, I was wrong!

Well, at first I wasn't, but now the new sphere has settled in I press the pedal 4x and the motor runs for about 7 or 8 seconds!!

But since I replaced the CV joint I'm hearing a "scuff scuff scuff" sound when braking. It's coming from the front right side... I imagine it's one of the pads. I may have put them in the wrong side (not that it matters a whole lot, but they will wear at different rates due to the pot pushing and the caliper pulling so if I put the pot pad on the caliper side and so forth....). It's just a bit irritating

Other than that, so far all is well...

I give it around 45 minutes

Should wear at the same rate either side.

Ok. New accumulator fitted. Full system bleed ( did it excessively to remove old fluid which was a horrible dark colour, obviously not been changed in ages!) now all nice new fluid. RAVE followed to the letter.
Now pressurises after about 20-30 sec, but still still comes on every 2nd or 3rd press ?

N/s rear piston is sticking I think. So brake strip and clean this weekend. Also bleed nipple on that calliper was completely blocked with crap!! Didn’t let anything out. Cleaned it through and bled it, but fluid very reluctant to flow freely from it, unlike others. Definite strip and seals needed.

All ABS sensors in properly. But Still shows ABS fault on dash when turned on, ABS light still on all the time though. Still nothing shows on Nanocom?

Assume dodgy n/s calliper isn’t helping matters? More I think of it, local Jrs4x4 Landy specialist sells two rear new callipers fo £46 so may just replace both and be done with.

Just need to get ABS light sorted as mot due next month.

ABS light isn't going out when you get over 5mph?

No. Stays on permanently.
Kermit_rr ? Not checked to be honest. I’ll check.
Cheers.
