Does any Vauxhall's brakes actuall do anything in the first 2 inches of pedal travel?
My Calibra has brand new EBC's on front and rear with braided line, has been bled till its totally air free yet has around 2 inches of travel before anything starts happening. When it does happen, its fine.
My Vectra I fitted new standard disks/pads front and rear, with braided hoses and again its been bled totally. Yet it too has around 2 inches of pedal travel before anything happens.
They both have exactly the same brake setup, 288's front and 286's rear. Both have exactly the same caliper too.
My old Focus (which I drove again this week, after 2 weeks driving the Vectra) stuck my face into the windscreen as its brakes work from the first 1mm of travel, and never even go past 1 inch of travel. Driving it again has made me realise how totally cr*p the Vauxhall brakes are.
I think the problem is due to the fact that the front calipers "bow" for a bit before they actually start putting pressure on the disc. This is supposed to be controlled by the springs which "connect" the 2 parts of the caliper together. The Vectra actually has new springs on it too because I found some, but its still as poor as it was before.
OK, it could be due to a worn Master Cylinder, but the pedals hold firm when pushed, do its not passing fluid through the seals.
It could be a simple case of adjusting the actuator rod which connects pedal to M/C, but this is just preloading the caliper which shouldn't be necessary and will definately increase wear as I've no doubt the pads are touching the disc whilst the caliper parts are flexing apart (as the pads are what is actually pushing the calipers apart).
Is it just a really poor design and all the calipers of this design do this, or do both my Vauxhall's just happen to have an issue.
Is there a different ATE caliper which fits, or did Vauxhall ever use a different manufacturers caliper which fits that hub/mount? A nice monoblock perhaps
Whilst you do get used to it after a few hours, it isn't half a sh!t braking system when you drive a better one.
Clearly 308's will have the same problem as they share the same design, posibly even worse as they have more give/flex inbuilt into their design to cope with the larger disc.
I want to keep standard brake parts on the Veccy, the calibra will get Brembo's if I ever uprate it.
Is it just mine?
