Hi All,
My E30 project is nearly done, the only thing really preventing me going out and enjoying it is that the brakes are performing terribly!
I have done a 5 stud conversion so up front it is running E36 M3 brakes and 318ti at the rear. The master cylinder is a brand new 25mm unit from an E32 and it has braided brake lines all round.
Basically, the brake pedal sinks most of the way to the floor before anything starts happening and even when you really stomp down hard on them the car doesn't stop anywhere near as well as it should, it's a real "heart in the mouth" moment.
We have tried twice to give the car a really good bleed on all 4 corners but to little improvement. No more air seems to be coming out of the lines anyway. The master cylinder was installed following the procedure in the bentley manual which doesn't say to bench bleed it before installing, could this leave a bit of an air lock in a brand new MC? Does it maybe need to be pressure bled instead of the normal 2 man method?
Is there anything besides it not being bled well that might be causing it?
It is worth mentioning that the brakes were just as bad before any of the 5 stud work was done, ie on the standard brakes, master cylinder and rubber lines.
Any advice would be appreciated.
