Put new pads on today as the old ones where down to the metal,had to get hold of aset of sliders as 2 where sized solid, now the thing is the pedal is hard without the engine running but with it running the pedal goe's almost to the floor, also if we press the pedal afew times the warning light comes on, looked at the vane pump on the back of the alt seems o.k.the pipe which goe's to the warning switch was full of oil? anyone on here known/seen this?
Thanks
Paul.
The sliders are an issue, I stripped mine down and applied copper grease. New pads on old discs take a while to bed in, as said in previous threads, brake lightly then release, do this many time on a journey if safe to do so, but don't overheat the discs., they will get better. Avoid excessive braking with new pads as this WILL score the disc, as it will create hot spots on the few points of contact.
When fitting new discs, always fit new pads.
If you brake several times (4-5) you will loose the vacuum in the servo.
Since you are probably only ticking over, the vacuum pump on a diesel, which is on the back of the alternator, is only reving slowly.
The brake pedal is hard when there is no servo vacuum, and when you start the engine the pedal does go down a long way, however once your pads are bedded in this will improve, BUT also get the slack out of the rear brake adjusters, first at the rear wheels then on the hand brake adjuster underneath the centre console. (behind handbrake) There is a download on this, my handbrake starts to come on now on the 3rd click, and the brakes have never been this good before.
Mine is the non abs version and have never really been that great from new, the front always pick up before the rear, as the weight always transfers to the front. Not had the rear brakes lock on their own yet.
I fitted Rossini discs (grooved and drilled) to reduce fade. this has made an improvement. Hope this helps, best regards, Rustic
