Unhappy sticking front caliper

Hi all

just been having a check over on the front pads to make sure there's enough meat on them to make it thru till wednesday when its booked in and noticed that the nearside front pads look to have been wearing unevenly (inside pad has worn more than the outside) but the offside have worn ok.

the worrying thing is that this will be the second time that this has happened and in the worst case scenario, it'll need a replacement caliper. as i said, this has happened before on the same side and a recon caliper was fitted.

is this a common fault or have i just been unlucky??

Re: sticking front caliper

Re: sticking front caliper

I've rebuilt several sets of 2pots.
Rebuild kit is very cheap (about 20 EUR) and what you do is just disassemble the caliper and replace all parts that come in a rebuild kit.

There are 2 things you need to be aware of:
- Caliper pistons are made from iron and are chromed. Therefore if chrome coating has come off on some places there is where the rust will form (because brake fluid absorbs water from ambient). Rust will seize the caliper again. Best is to replace piston if it's rusted (chrome has gone off) severely. You can also buy steel pistons off ebay. I'll also try fabricating aluminum calipers myself, but this method has not been tested yet.
- These are floating calipers, which mean that pistons are only on one side and whole caliper move left and right on 2 rails. These rails usually also like to seize, which then results in uneven pad wear (in most cases this is the main problem like (i think) in tom73 case). Fortunately there is an easy fix for this: just remove caliper from caliper and pad holder and lubricate these two rails - there is no need to disassemble whole caliper...
