Hi,
I have a strange problem.
Recently i changed rear brake pads, removed air bubbles from the brake system and all was ok until today. When I brake the brake the pedal goes slowly deep. This wasn't earlier.
But the braking performance is normal. I not shure 100% if brake liquid is missing (I'v checked today)so I will check tomorow again.

The pads and pedal may feel a little strange untill they have bedded in,  do your checks and if nothing found give them a few hundred miles to settle.

Thanks

well, the brake fluid missing. When I brake it seems that work only front brakes because the pedal goes very deeply. When I restart the engine for a bit of time works both brakes....

Symptoms are air in brake lines, or an inverted seal in master cylinder.

Are you losing fluid? is there a leak?

[supersaw]

Yes, somewhere is a leak I think it is something to do with the driver's side rear wheel because it is all in strange grease.

Remove the wheel and strip brakes from back plate and clean all parts with spray brake cleaner, you will most likley find that the rear wheel caliper is leaking past the piston bore or you have not tightened up the bleed nipple or a split hose,  untill you strip it you wont know for sure.

I think the problem is with this bigger rubber ring.



 I think that thru this ring is a leaking. Tomorrow I will by a caliper repair kit.
