I have what I consider to be quite a bit of travel in the brake pedal on my car and wonder if anyone can make any suggestions.
I have standard non ABS Sierra front callipers which are re-manufactured and standard rear callipers that have had new piston seals fitted. The pedal box is OBP floor mounted bias box. All discs and pads are brand new.
The pedal feels quite spongy but does not seem to pump up any more, anyone experienced similar? Ive used rally cars in the past and bias pedal boxes seem quite firm. The only option I can see is to move up to larger master cylinders.

You might have to unbolt the rear callipers to get the bleed njpples at top when you bleed them, otherwise you can't get all the air out.

I'm with Britishtrident - bleed the rear calipers again.

Even when they're mounted correctly (bleedscrew at the top) it's difficult to get all the air out of them.
