Brake problems...
Cluelesstom - 9/7/18 at 08:25 PM

Hello, just got round to fitting the master cylinder, first bench bled it and then bled at each wheel.
now i cant seem to get much at all on the pedal, ive also noticed that there are small air bubbles coming from the master up into the reservoir,
does this mean ive failed to bleed it correctly or is this master cylinder shagged?
TIA.

It took me over 2 litres of fluid to fully bleed my brakes the other week. A proper pain in the arse!

What method you using? I bought a gunson easibleed, and in the end had to go back to the one way valve and pedal pumping method

i was using a vacuum bleeder then resorted to doing it as you said just pumping and closing, when i put the pump on, it comes out pretty clear, with not alot of air if any.

ill give it a good go tomorrow again, are the bubbles concerning in the reservoir?

I use the ezebleed and never has an issue. If you have concerns over the MC id replace it for the few quid they cost

I have replaced it :S

Did it make any difference?
On your calipers and drums or whatever, are they fitted with the bleed nipples at the top of the units?
My mate managed to fit his with the nipples at the bottom, it was a while until he sussed it.

the old previous master just started passing its seals and the pedal was just going all the way back but the brakes were decent before that, the nipples on the rear drums are on top same with the front calipers, I’m going to run a few litres through each wheel using that vacuum kit tomorrow and see if that works if not I’ll bench bleed it again...
Thanks for your help

Someone wouldn’t happen to know the measurement between the mounting holes on a fiat 124 master?

Not sure how you can be having issues with this, I use an easibleed regularly and it's quite fool proof even with modern ABS systems & was the only way I could bleed the Landy's brakes myself.
