ABS churning after brake bleed
Hi guys
Newbie here. Just joined after buying my son a 95 Accord coupe Ex. 4 Cyl with an automatic. 139k.
My question...I took it to a local tech for timing belt/waterpump. He did that and noticed my brake pads showed some wear and suggested pads and rotors..no problem. I asked him to change brake fluid while he was at it..since it had never been changed.
Got it back and now noticed an intermitant churning sound(like a faint grrrr) coming from the abs system. Low on fluid? Air in the system? Just wandered if it was anything I could check? Owners manual says take it to a dealer.
Thanks!!

Thanks for the advice....it really didn't seem like that big of a deal. I mean the bleeder is right on top...I read the procedure and it sounded pretty straight forward. The only question I had was where do you refill the reservoir for the abs...or do you just fill brake reservoir. I think my problem might be it is slightly over filled.

Suggest checking the ABS code. See DIY forum for checking codes on Engine/Trans. Same procedure for ABS but codes are flashed by ABS light as short flashes; code 44 = ffff-p-ffff.
It is possible the repairman damaged a ABS wheel speed sensor to cause the problem, but sounds like following.
The accumulator or ABS modulator may be leaking. Whenever pressure drops, the pump kicks on to rebuild stored pressure. Hard to understand how repair could have caused this problem. He would have had to bleed the brakes to replace the brake fluid. Unless he decided to try to replace the modulator reservoir brake fluid also.
good luck

If the abs res is low.....Yes, right behind the drivers headlight..ok a foot or so, there should be the res, there should be a 1/2 dollor size black rubber plug...remove it, under that is another clear plastic plug with an oring...remove it...add slowly as it is a small opening.
