Sometimes when I hit my brakes, I'm not always sure if I'll stop. There are no warning lights coming on but at times I have a full pedal and at times I don't and have to pump them to get the pedal back. This started out as a rare problem but has increased to daily. Recently the pads and rotors (all 4) have been replaced, no leaks were found when checked and fluid level is correct. Has anyone else had this problem?

 

no.
car?
mileage?

 

master cylinder bypassing internally?

 

now ill guess. they lost fluid,got air in lines.
i heard its tricky to bleed abs,whiz bang brakes.
im guessing they were ok b4 the "brake job"
more guesses later

 

They haven't been bled properly after the brake job..

 

it's on a 2006 h3. the problem existed before the brake change too, just more intermittently.

 

ditto

 

sounds like to me the abs module isin't working properly, I had a similiar situation on a 1998 s10 Chevrolet Blazer, the dealership explained to me that the abs module wasn't dispersing the brake fluid to the wheels properly, to this day I still don't understand but it was under warranty. Just sharing my story to try to help out.... good luck
