156 brakes won't bleed??? open to any ideas!
hi all, after a recent fiasco of having to do my clutch twice (I've learnt to avoid transmech and carparts4less) I managed to get another few days of trouble free motoring until yesterday on my way to work, had to brake quite harshly and managed to burst a brake line.
It was the one that ran from the drivers side front to the abs unit.
I managed to drive it home very carefully, leaving a trail of brake fluid behind.
Rather than just replacing the last foot or so, I decided to remove the entire pipe which was more difficult than it looked (they must have started with the brake pipes when building the car) and made up a copper one.
since re-fitting the brake pipe I cannot get the pedal back.
I have bled all 4 corners but there is hardly any pressure at all and the pedal still goes to the floor.
there is barely a trickle from the side that was replaced.
I have undone it at the abs unit end and had someone press the brake and hardly anything comes out, so its not the pipe blocked.
with the engine off, there is a definite 'notchy' feel as the pedal gets to about half way but this is not there when the engine is running, however the pedal still goes straight to the floor, just a bit smoother with the engine off.
I'm guessing its the master cylinder has lost its seal, probably due to being disturbed, but could this be down to air in the abs unit?
I was going to undo the pipe from the master cylinder to the abs unit and have someone press the brake and see if it squirts out but didn't have a second person with me today to press the brake.
if there is air in the abs unit would this cause the car to have practically no brakes at all?
if anyone has had this problem before or has any suggestions what I should be doing before attempting to get the master cylinder off I would appreciate any ideas.
