Hi All,

I've recently replaced the front passenger side hub, disks and pads all round and a seized rear caliper. I did manage to lose a reasonable amount of brake fluid when changing over the caliper. I topped up the brake fluid, bled all the brakes in the recommended order just to be sure and things seemed ok.
However... every now and then when pressing the brake pedal it judders or sometimes feels like it snatches or kicks back. I've not noticed a pattern to when it happens but it does seem slightly more frequent after standing overnight. If I release and reapply pressure then it's fine again.

I've rechecked each wheel, several times now, and I can't see any obvious issues. If it was a warped disc or something I would expect the issue to show itself more often.

I'd really appreciate any suggestions you might have as this is really getting on my nerves. Is there any way this could be a problem with the master cylinder/servo?

Cheers,

Mark

Is it the ABS activating?

I don't think so. It's definitely not the same noise/feel as when TC kicks in and the light doesn't come on ( although I'm not sure if it should ).

This has now happened a couple of times when stationary. Start up, press the brake pedal before moving - judder felt through pedal.

Very odd but it rules out a lot of stuff.

If it happens when stationary it's just the ABS self testing. They all do that sir.
