    How much travel on your brake pedal?

    I'm unsure if my brakes are too spongy after the 280mm front upgrade and rear disc upgrade (all 4-stud).

    I can manage to press the pedal right to the floor at standstill, and I don't think I could do this with the old brakes. They do seem to have no issues slowing me down, but if I can push the pedal to the floor then I'm assuming I'm losing some stopping power as I'd be able to do this when braking harshly if ever needed.

    They were bled fully with new fluid, but I'm unsure if there could still be air in the system? We used a one-man setup to change the fluid appeared to work fine.

    It's an easy bleed kit (Ffoeg's actually, not mine) where you put a tube on your tyre valve to push new fluid through, I've driven around 200 miles on the new setup now.

    well vauxhall quote 100 miles for bedding at my place,so that shouldnt be an issue,so id suggest,get your mate to help you do a two man bleed, ie pump up,hold down,release nipple etc you know the score im sure and remember bleed from furthest brake from driver first so nsr,osr,nsf then finally osf

    i have just had some new pads fitted at the garage and mines pretty similar i have to push the pedal a bit further down to feel any braking power what so ever...

    it still stops but requries more force than it used to,

    from a novice point of view is it easy to bleed the brakes (assuming this is the issue but shouldnt the garage have done this?) and if not how much am i looking to pay for it to be done?

    cheers

    The brakes were bled in the correct order so no issues there. I think I'll give it a week or two and see how they are going, and re-bleed the system again with (if I can find some) different colour brake fluid so I know it has been fully bled. Current Halfords Dot4 fluid is a slight yellow colour.

    I think it'll just need to bed in more.

    Also the master cylinder on the 4 stud is smaller than the 5 studs, which has something to do with it but I forget what.

    Hmm, did someone else not recently confirm that the same master cylinder is used on all MK4 models?

    I could be thinking of the size of the piston on the caliper being larger ?
