Hi,

Can anyone confirm my suspicions before I fork out £350 for a new Master Cylinder...

My Berlina 2000 RHD brakes were at the bottom of the pedal travel and not very effective OK to stop but not in a hurry.. so i have stripped the front calipers and installed new piston seals and dust seals as both were not pretty.

Now 3L later of Dot4 fluid i still get very very fine air bubbles in a constant stream as i bleed the two front calipers..

i can now drive the car and with a quick pump the brakes are great but on a first push of the pedal the brakes are similar to how they were..

i suspect a small amount of air is passing the master cylinder piston seal on each stroke..

Any ideas before i go nuts please :)

RHD, you have two boosters? Have you confirmed that they're OK, not filling up with fluid? It's common as they age.

Hi, yes two boosters. they are both relatively new (been refurbished not long ago)..

The MC bleed nipple will not bleed and is very old this is why i think its the MC.

thanks,
