Hi All,

As the title states, I changed my rear pads and discs as the rear left pad was completely gone, rubbing metal to metal on the disc.

Since then, I have noticed excessive wear on the same wheel and the alloy is always a lot more warm to the touch compared to the rear right.

The guy that changed the pads and discs said that it's probably cos the caliper has gone on the rear right and as such, excessive pressure is being exerted on the rear left.

Is this is the case? Is this a replacement caliper jobbie and if so, which side?

Could be a slider is stuck. If you live in the north salty winter area they could have become rusted or dry.
Take it to another mechanic for inspection.

Thanks - whats the slider and can it be cleaned/fixed without having to replace the entire caliper?

Possibility is that your caliper is seized or you're activating traction control a lot more on that side depending on the turns.

Thanks - What's the most cost effective place to buy a replacement?

I'd say a sticking caliper is the issue esp. if that side is showing signs of increased heat.

Could buy a new caliper from the likes of ECP etc.

Think I've still got my rear calipers I removed when I did the Alcon upgrade. You can have the pair for cheap if you wish?

It will definitely start to degrade the wheel bearing.

Same thing happened too mine same wheel too, it was the piston in the calliper all rusted up because the rubber boot has a metal ring that holds it on the calliper and this had rusted causing small bits of dust and water too get onto the piston, when I stripped it the rubber square seal was kind of out of shape and hard think this was due too the excessive heat,
I got a calliper rebuild kit from big red brakes £20 and job done need too bleed brakes after obviously.

It is possible if the OP takes alot of left handed corners. The thing is here in the UK, round abouts only go clockwise so you'd expect more wear on the right rear tyre really.

May be worth checking wheel alignment, speed sensors etc.

The best thing would be to have a logged drive to record when the brakes are activating. I know the OBD port can provide the data but I don't know the software needed to read and record it.

Update, had the caliper replaced. Upon inspection of the old one, it was clear that the piston had seized.

Now, I can't recall if the mechanic put the two plastic dust caps onto the new caliper? Can I check by just getting the wheel off, or will the new caliper need to come off?

If you are talking about the ones that go over the long sliding bolts then you can check by just putting your hand round there and feeling, or just whip the wheel off and you'll see them from behind.
