Brakes are hard and takes a while to stop.

[951's 330i]

Hey everyone just like the title says, problems with my braking. Tried bleeding them out but nothing. Even at like a 10mph roll, slamming them wont stop the car quick enough. It goes about half way down and is stiff.

Any help is welcomed.

Check your brake booster vacuum line.

if they are hard it's most likely a problem with your brake booster...dunno how you'd check on that....make sure that it's hooked up and the vacuum line isn't clogged and all that...

For sure its hooked up. But does having a RB in there make any difference?

when did it happen? one day driving or after the swap?

do you still have the check valve in that line?

if so is it installed in the correct direction?

Car has been like that since i bought it. Swap was done before i bought the car. BUt since i had to try to figure out why the hell the car would turn off on me(THANKS AGAIN BARDABE!!!!!) i never paid attention to the brakes. But now im working everything out now that i can.

replace the whole booster it will take like an hour to do. i had the same issue on my s13 it wouldnt stop fast even from a 10 mph roll

Just check the line first before you go throwing parts at the problem. Make sure it's not dryrotted too.
