Brake click?

[clickman]

Did my fronts a couple months ago, Zimmermann rotors, Ate pads, new stock caliper bolts. No problems until I went on a 2000 km trip thru the Rockies a few weeks back (only way to see them, with the top down).

At one point, I noticed a click coming from the left front, intermittently, on both application and release of the brakes. It's still there, intermittently.

The caliper bolts don't look loose, and I haven't pulled the wheel off yet to have a real good look, but does this sound like a sticky caliper piston?

If so, is there any easy fix short of replacing the caliper? Are rebuilt units available?

Did you fit new anti squeel plates?

These plates are stuck to the back of the disc pads and have two alloy pots which slide inside the centre of the caliper pistons, If you have not fitted these the pads will move a little within the caliper and can cause a click - most prominant when you reverse and apply brakes then go forward and apply brakes.

If you did not fit them at all then you can take them off your old pads by using a stanley type knife, just push the blade between the backing material and the pad, work it round the edges then a screwdriver pushed inbetween, give the screwdriver a twist and the squeel plates will start to seperate from the pad.

Put the squeel plates into your calipers first, then the pads, then go for a spin, the heat generated will re-stick the pads to the squeel plates and your clicking will be gone

Everything I've heard and read indicates the anti-squeal plates are for the Boxster "S" and not the base Box like I've got. There were none on the previous pads, just the regular flat backing plate.

I took the wheel off yesterday and pulled the pads. Nothing obvious, other than a lot of dirt collected on the lube on the metal plate on the back of the pad, which I assume is normal.

We'll see in the next few days...

I had a similar thing after getting my front brakes done. It sounded like a clap of the pads on the disc or something. It happened a few times but I haven't heard it lately. I didn't think about it but it was always as I was backing out of the garage and then going forward as described in the post above. It also happened a couple times after washing the car and pulling into the garage but also per the post above I had probably backed the car out before washing then went forward to put it away afterward. Anyway, I don't think it's happening any more. Yours may go away over time.

So after taking the pads out and checking things out a couple of weeks ago, the click/clap is still there, intermittently, on application and/or release. Frustrating. Any more suggestions out there?

Try different pads??

Have the pads the same measure ( especially the height ) as the originals? Is the rotor installed and locked on the hub with the two small bolds? Are the wheel bolts locked with 130 newton ( 13 Kgm )?
