done a search, but just found topics on pads n discs squealing....

Right....

when i press the brake pedal, it goes hard but not much braking power... then something squeals a bit, then the brakes bite harder.

Any ideas?

what pads are you running? How much life is left in 'em?

I was having all kinds of brake issues - didn't feel much bite, vicious shudder when hauling down from big speeds. Replaced them with Endless Super Sports M (street pads) and I got all kinds of bite now. Took a look at what was on the car - Endless metallics, had chunks of the pad come out They look like racing pads, which would explain the lack of bite on the street.

If it's not the pads (which I think you likely have already ruled out), it might be something in the calipers. If those check out ok (pads seated correctly etc, no sticking pistons) then I'd just work backwards to the brake master cylinder. Or maybe it's from the other end, and your brake pedal is sticking or hanging up on something, hampering how it actuates the brake cylinder?

had the pads out, gave them a good clean. They looked to be pretty standard items. Sure it isnt the pads.


Doesnt seem to do it when car is stationary though so ..... confusing

fixed

fitted a master clylineder stopper, and the weird pedal feel, and squeal has gone

that's an interesting bit of kit there, what's it designed for?

My brake pedal squeaks occassionally from the inside of the car as well, but I think it's just the pedal itself asking for a bit of grease

stops the bulkhead/MS flexing under braking.

Seems to have given a much more positive brake pedal. Quite surprised as i wasnt expecting it to do much

I wonder then if your braking problems were the result of the brake booster flexing the bulkhead then. Hmm, seems a simple enough piece of metal to throw in under the hood

Where did you get it from?

 

[anthonymcgrath]

made a difference on mine too - braking feels a bit less spondgy due to the master cylinder not flexing toward the front of the car on hard braking. nice simple mod and usually on ebay for 25quid tops

 

[Adam Kindness]

got it for 18something off ebay, from HongKong.

I know this has cured your problem, But it might be wise to keep looking for the original fault as well, or at least bear it in mind the next time your working in that area and keep an eye out for things.
