Vibration/noise under braking..

[RS13]

My daily makes a loud noise under straight line light braking at low speeds, it sounds as though the RF tyre is rubbing on the inner guard. Has a slight vibration through the pedal as well. Any braking harder than a light push and it goes away.

- There is no evidence of chafing anywhere, the guard is miles away from the tyre.
- I've had the brakes completely apart twice, there is nothing obviously wrong, plenty of meat on the pads. All nuts and bolts on that corner are tight.
- All suspension bushes/links look fine with no play. The inner CV has a little play and is getting replaced soon (light clunk when taking up drive) but I don't see how that could make the noise.
- The brakes still pull up fine and evenly, no bias either way.

My best guess could possibly be the pads chattering (they came on the car, look like Repco specials and occasionally squeal when cold), has anyone ever come across anything like this before?

Any ideas or advice would be appreciated, I'm beginning to think I'm missing something obvious! lol.

Cheers.

do the calipers still have the spring steel clips in place?

used to get a bit of noise on one of my cars that was missing these, cos the pad was shifting round a bit in the bracket.

Are the caliper sliders seized? I had a graunching noise that was finally found to be because one slider had seized so the pad moved around.

I've had a small shard of metal in my pad before... picked it out and was good as gold. Lao check thickness of discs.

Checked your wheel bearings?

Thanks chaps, I've had another good look and can rule your suggestions out. There appears to be a fair bit of play in the outer CV knuckle and bearing cage assembly, enough so that I can move the driveshaft a couple of mm either way until it takes up driving the wheel. As it seems to be the only thing on the hub assembly with obvious wear/play, I'm going to replace both CVs when I get a chance and hopefully that sorts it.

Cheers fellas.

let us know how you get on.

shouldnt be that much movement there.
