i was driving along and started to hear a ‘flat tire’ type noise…pulled over and thats when i found that i wasnt stopping!
when pulled over i found the bottom lip on the dust sheild was broken so thought that was the knoking but didnt explain the lack of brakes!
checked the fluid and was full…checked there was no leaks and was ok…checked every thing was still there and all look intacked!
it was dark and cold so took it very easy home.
took the wheel off this afternoon and took off the dust sheild. when spinning the wheel it was still chatchin making noise and it looks like the disk could be warped as it gets to a ponit and hits the pad. i was looking to upgrade the disks and calipers anyway to 4 pots so not too bad just a bit early!
so the only thing i can think off is the servo or master cylinder are knacked giving me no brakes?
dose anyone have any ideas or had this befor?
(i did search!)
My boss was driving along and his brake servo broke cause the brakes to stop work he then hit a traffic island. So buy the sounds of it the same’s happend to you. Did you have any braking atall?
Very probably the wheel bearing has failed - and the disc is wobbling about - and pushing the pads back into the caliper. To check -car not moving - pump the pedal a few times times - does it come up solid ?
mini-jon..i had a very slight bit of braking but only when the pedal was on the floor! the servo is what i thought it was going to be..but theres no way of testing it or is there?
bmcecosse..i did try that and prity much stright away the pedal goes solid..would this be the noise im hearing or could it contribute to the failed brakes?
danrock101..the dust shield broke where the bottom tab is where it bolts. i did look but its not close enough and dosent seem to have caught the pipe atall.

I agree with Roy that this sounds like a wheel bearing issue. That wheel catching that you reported is a symptom of a failed bearing.
Bmcecosse (Roy’s) suggestion was that your wheel bearing has failed and the implication is that the brake rotor was not spinning in one plane but with a wobble. The wobbling disk will have pushed your brake pistons WAY back into the caliper. Normally the pads just kind of rest gently near the disk with very minimal gap. That first pump of your brake pedal pushed the pistons back into position but took most of the pedal travel to do so. The next pump or two (made quickly) benefited from the pistons and pads being back where they should be… resulting in a firm pedal.
Get the wheel bearings fixed then test drive the car. You should find everything is better once the bearing issue is resolved. However, assuming it is a bearing failure you must now ask why that happened and what damage it may have caused to the hub or CV joint.
ok so i got new bearings.
now i done the nearside before and all went well. but im stuck at geting the crown nut off. ive tried with a lever bar (scafforld pole about 1.5 metre long) heating it with a propane blow torch.
it just wont budge atall its just spinng the wheel and rolling backward!
i tried both ways just incase it was the wrong way!
has anybody got any other ways of or ideas of undoing it or how has anyone done it befor? can i grind it off ive got a spare. but just want to ask befor hand!

It sounds like you are having difficulty with the left-side and by rolling backward it sounds like you’ve been trying to turn the nut clockwise to remove it. Though the rear wheel hub nuts are “handed” the CV joints up front are not. You need to turn them counterclockwise to remove them on both sides of the car. By using the heat of a torch and turning them clockwise with a 1.5 meter pole you MAY have just snugged them up so much it will be true heck getting them loose.
I suggest re-application of heat, chocks under the front wheels, and a friend who can sit in the driver’s seat and mash the brake pedal for all they are worth while you turn that 1.5 meter pole counterclockwise.
