Brake pad replacement

[EazyDuz]

Can anyone give any tips on removing the caliper and changing brake pads? Pistons seem fine just the pads are a bit knackered, so i was wondering if i should clean up the caliper as well. How would i go about removing the pistons and cleaning them up, or is that not needed?

On all the bikes I've had - removed pin - take out old pad - push piston back - insert new pad, with a bit of copper grease on the reverse.

Only you can judge if you need to clean anything as we can't see it.

Literally a 20 minute job. Get a manual.

If you do decide to clean up the pistons you've got two choice the quick, easy but not that effective way or the harder, slower but much more effective way.

You can take the pads out and clean the outside of the pistons with some solvent then push them back into the caliper and pump them back out using the brake lever (as far as you dare without them popping out!). Repeat process and it'll help if you breaks are sticking (at least it did when mine were before I followed the more in depth procedure below)>

The second method involves taking the caliper off the bike and popping the pistons out. I did this using a compressed air line blown down the hole where the banjo bolt would normally be and a bit of rag stuffed between the pistons so they don't smash into each other. Once you've done that you can give them a proper clean up and replace the seals before re-assembly (at this point I painted mine as well). It's not a hugely hard job as long as you're careful and a haynes manual will certainly help.

Unless you've been having problems, I'd leave the pistons alone. Just remove the old pads, use some brake system cleaner to remove any built up crap on the caliper and fit new pads.

If you're unsure how to change the pads then get a manual for the bike - it'll be an investment anyway.

If the pistons look fine and the brakes are working ok then just give them a good clean to remove any build up of dirt. Don't take them apart unless you need to, not worth the effort and certainly not worth the risk of getting it wrong.


EDIT: yeah, what Islander wrote
