Bleeding Broken Brakes

[DAZZERB]

i had the same problem on my 16 v the problem was there was a gap inbetween the caliper piston and the brake pad when fitted, unscrew the piston, then push the pads in so they are tight, before you bleed them this should tighten them up

The piston should automatically adjust itself.

When I changed the calipers on mine I had a nightmare bleeding them, I jacked the back up and left it on stands overnight.with the pressure regulater clamped.

I used a pressure bleeder whilst pumping the pedal to get them to come up.

I've read its ok to pump the pedal when using a pressure bleeder. Isn't that a bit iffy though?

You need to keep a fluid barrier between the air pressure and the master cylinder when pressure bleeding.  It's OK to pump the brakes but you REALLY need to watch the fluid.  It goes through at a rate on knots when under pressure.

Yep, i've always found it ok just to use the pressure bleeder. Just got to be careful how much pressure is used.

I found with my brakes that the pressure bleeder wasnt getting it all out and had to pump them as well to get them to come up.

Brakes now sorted.  A combination of bleeding them and bedding them in seems to have done the trick.  Passed MOT yesterday, every wheel could be locked up on the rollers.

Pedal still a bit spongey but I can live with it as they stop so much better than the old ones.
