2.6 brakes
« on: 01 March 2012, 21:23:33 »
Hi, i have replaced discs & pads all round, also all brake pipes including the flexi's.  My brakes still feel spongy, if i keep my foot on the pedal it goes down, not all the way, but it doesn't feel right.  Does anyone have any ideas as to what migh be causing this??  Could it be the master cylinder, or the ABS pump??

Kind regards

Paul

Probably air in abs mod - needs TechII to exercise modulator to shift whilst bleeding. ;)

Were the bleed nipples opened when winding the pistons back into the calipers?

Could be that a seal in the master cylinder has inverted.

Although this is often quoted IMHO I think there's more urban myth to this that fact! Brakes have been bled in their millions over the years without bleed nipples being opened before pushing caliper pistons back.


My brakes were bled & bled & always felt spring, rather than spongy, but were put back to 'normal' after new discs were fitted. Inboard sides of discs wee both fubar'd  ;)
