Pedal Travel

[davidn]

How much pedal travels is normal on the brake pedal, I am getting about 1-1.5" before anything happens. I have pressure bled the brakes, new fluid, calipers and braided hoses. Pumping the pedal makes no difference although there is a pronounced wheezing from the servo probably` during the first 1-1.5" of freeplay. Is this normal?

That's not much travel. Mine wheezes a little if I get into the footwell and listen carefully too - it's only an 'internal' wheeze though.. I think they all do that ... hope so.

BTW. Not sure if it would be a reason, but check your vacuum hose isn't split/worn out/collapsing. On the Chimaera there are a few points where is can rub through.

New pads as well. You may find that the travel and feel improves after bedding in and that can take a few hundred miles.

When you bleed the brakes make sure that you firstly remove any vaccum left by pressing the brake pedal a few times until it stops wheezing, then bleed the system.

This happened to me recently and I couldnt work it out even with new disks and pads fitted, this trick cured all.

Thanks guys, can't remember if I pumped the pedal to remove any vacuum, using the Esi-bleed method. I'll give it a go though.
Thanks

What difference does clearing the servo of vacuum make? It's not linked the the hydraulics, it just provides a helping hand.

Any of you got a view on my brakes problem- see Bleeding Brakes thread?
