Just fitted hydro to my e36 bled bled bled and bled some more, all air removed pedal feels good and then start it up and drive and the pedal is spongy as anything and the hydro does naff all Fitted in line of rear brakes single cylinder as its an early e36 with only 1 rear brake line, loads of meat left on the rear brakes and locks up ok on the mechanical hand brake Anyone help me ?
The pneumatic bleeders are quite good for bleeding up hydro's. I would of thought a pressure bleeder would of done it.
^ not that relevant, a hydro will stop the engine no problem. It's not bled properly, they can be a pain, IIRC I did it by pressing pedal, open bleed, pedal almost all the way, pull hydro all the way, close valve, release hydro, release pedal. It was quite some time ago though, just try every sequence you can think of until it works.
when you're bleeding it, you're holding down on the foot pedal and holding on the handbrake, right? i don't think you did. sounds like some air has been pushed into the rear brake lines.
When you bleed you need to open the nipple, then apply the pedal. Otherwise you get cavitation in the fluid and it wont push the air out as effectively.
i just pulled the hydro and pumped the foot brake untill i couldn't hold the hydro up any more and then bled at the back. Ignored the hydro for the fronts. Did this about a million times
Just had another go bled loads of different ways Pedal rock solid hydro rock solid,put a bar inbetween the wheel studs and with the slightest pull on the hydro could not turn the wheel so happy days so I thought then tried it up the road and its a little better but not locking like I expected ;( so ill beed it another 100 times again tomorrow and see if that helps any Thanks for all the replys guys
i had a similar problem with a crap pedal and the hydro was shit. what cylinder are you running. if it's a 0.7 try swapping it for a 0.625
How I did mine was- Bleed it up Take it for a drive Bleed it again Went to a drift day, focused on giving the hydro as much use as possible Bled it again and it was fine. We were bleeding the manual way, press brakes down pull hydro, open nipple, close nipple, repeat.
put new rear pads in. They're like £12 from euro. Don;t need to be fancy ones but the ones in there are probably 10 years old and glazed to fuck.
