bled brakes, but still not working that good

ok, i bled all 4 brakes today. they work somewhat now, but not like they should. i have to pump them a couple times every time i go to use them in order to make them work. i bled each one about twice. do you think that i should have done it a couple more times on each wheel?

If you have to pump them that is a symptom of the master cylinder bein' bad. Just to make sure you bleed it right start from RR,LF,LR,RF and do each corner at least 4 to 5 times. If it still persists then it is the master cylinder

actually come to think of it, i did the LF before the RF and i only did it like twice on each. i'll have to try it again tomorrow. does it make a huge difference that i did the LF before the RF?

You always start from farthest from master cylinder to the closest.

Either way, I bet your master cylinder is done for.

try bleeding your master cylinder first, maybe some air in it

how do i do that?

Are you just gravity bleeding them? If you're just gravity bleeding them it might not be enough, even though it's always easier to start w/ gravity bleeding.

What you do, is you get someone to sit in the car, and when you open the bleeder valve they push the pedal to the floor, and they hold it there till you close the bleeder valve, then they can release the pedal. Make sure the valve is closed before they release the pedal though, if not you will suck air back in through the bleeder...

Invest into a set of speed-bleeders. It'll save time and sanity.

yeah, i was having my brother push the pedal down while i bled them....he might have let the pedal off before i closed one or 2 of them. are speed bleeders the ones where you only need 1 person?

Yes, but when I redid my TA's brake system, I still had a friend press the brake pedal down. I ran a hose (cheap vacuum line) off the bleeder into a clear cup of brake fluid, that way I could see clearly if there was still air in the system.

SmashThat · Feb 8th, 2006, 01:07 PM

what was the reason for that? so you could see if there would be no bubbles when it was all the way bled?

SuperSentra4203 · Feb 8th, 2006, 02:02 PM

Yeah, you'll bee bubbles in the fluid if there is still air, but don't stop right away, continue for a bit more to make sure it's all out, sometimes air will be mid-line and be a pain to get out. Make sure you do not run your master cylinder low!! If you do, you'll have to start over and prolly bench-bleed the master cylinder.
