Brake peddle clicks and sometimes nothing there....

He probably means the accumulator, this keeps the ABS pressurised - less than £200 to buy

The modulator is not the accumulator. It is the valve rather like a master cylinder that distributes the pressure to the brakes. It can modulate to pulse ABS independently on each wheel. Big bucks to replace that.

Hi,

I have a p38 and just recently there was a little click when I pushed the brake peddle, then the brakes worked. id di this a few times, but not every time.

Yesterday I pushed the brake peddle and nothing, it was really lose.
pumped it and they immediately started working again.
Was a bit of a shock, I can tell you.

So took it to the village garage, he stuck it on diagnostics and said that I need a new brake master cylider (modulator). the big lump at the back he told me. I am a bit think, so he keeps it simple.

Sounds very expensive, more that the cars worth LOL.

Hi
I've been living with this kind of problem for months and have been working my way round the system trying to ID the fault : I have renewed accumulator, bled brakes, replace ABS pressure Switch , replaced relays.....still have the problem but what I have found is that if I take an earth to the BY wire on the Pressure Switch that the pump runs. I therefore know that the pump itself is not defective. I have rigged up a manual press switch which enables me to fire up the pump.
I suggest you find out if your actual pump is actually deceased before you lash out serious money on a new one.

I think I am going to replace the washers.

I am trying to buy the kit, however....

Will keep trying, not sure what else to do.

Thanks again.

I get a click with mine but there is always (touch wood) plenty of braking behind the click. Having looked at my disks the have trenches rather than grooves warn in them but the garage says they have a few miles left on them yet but that they will need doing fairly soon. Would very warn disks create that slight resistance and a click or could I be staring down the barrel of something more nasty? As I say, the brakes work well and I've tried emergency stops at 70 on quiet country tracks. The brakes are probably next on the To-do list but just wondered if they are a likely culprit before I have them done.

If they're that badly scored I'd get cracking on that To-do list pretty sharp and I'd bet your pads will be fairly worn too.

A few people I know have taken the discs to have them turned, basically ground smooth on a lathe. Its really just a short term solution and only if after the process you still have the minimum required thickness (someone will come along and tell you what that is).
