HI there,

I am about to replace the rear brake pads on my Ten since they are knackered.
I had a look to my Haynes manual but I would like to clarify a couple of things before proceeding.


1) Only one of the brake pads is wasted (the one sitting on the cylinder). Is this normal?

2) Do I need to buy a tool like this to take the pads retaining pin?

Do I use gently the hammer to the the pin in and out?

3) I read that I should put some copperslip on the retaining pin before putting it back? THe brake pad is Ferodo brand and it has already this blue compound on the back and edges of the brake pad.

4) How do I disassemble the caliper from the swingarm mounting bracket? In the Haynes manual it says "slide it out"... no need to unscrew anything, just push away?
I probably dont need to dissamsemble the bracket from caliper, but I wanted to properly clean the caliper and put some copperslip on the pins.



Thanks and sorry for asking so many questions

hi mate, i have mine off at the moment so here goes
i have the rear wheel out at the moment so once thats out caliper simply slides off its sliding pins the ones with the little rubber boots on them, pull out the little clip holding the brake pad pin in and then give the pin a little tap through the hole on the right hand side as it has a little expanding clip on the left hand end of it, once thats out both pads will fall out. give everything a good clean and i tend to put a little bit of copper slip where ever the pads touch the caliper.
not sure if you can do this with the wheel still in as i didnt look as my wheel is already out i thought i would clean caliper.

Got the pin out so that pads are now off the caliper.

Problem is that the caliper will not come off the bracket. I reckon the sliding pins must have seized. Any suggestions on how to slide the bracket out? I put a bit of wd40 but the "rubber boots" will not allow much in

Also, here is a picture of the old pads. You can see the difference in use between the two (I know, I should have changed the pads before )



Cheers

yep sounds like you caliper is siezed mate which is why your pads are like that, good luck sorting it out they can be a *******! you might have to disconect the caliper from the brake line and do it in a vice or you could try gently taping the bracket off the caliper with a rubber/hide malet or maybe a bit of leverage between caliper and bracket.....good luck

I sorted out a previous bike with the same seized rear piston and caliper slide.

To fix the piston you need to pump the pedal so the piston becomes exposed enough before coming right out (and making a right mess) then use fine grade sand paper to smooth out the ridges along the piston that would have built up. Working the piston in and out should free it up. I use a pair of pipe pliers to get a difficult piston back in (wider jaws).

The slides can be the same but use plenty of grease during reassembly. Could be caused by water ingress due to damaged rubber boots? A �5 fix.

Rear calipers get hammered as it's more difficult to access to strip and clean reguarly.

Hi,
Piston looks fine. Looks like is the sliding pins that probably got corroded and hence the caliper is stuck.
This seems now like a bigger job than replacing the brake pads was
Good that I realised about the problem though

Thanks

�5 fix The 0 button on your keyboard must be broken!

I had to fit new boots on the sliders (as one had a split) when I last changed my rear pads a few months back - they were just shy of �50 from the dealer. Fifty quid for two small bits of rubber! Searched high and low for pattern items to no avail.

Apart from pads, spring clip, boots and pad retaining pin, there is nothing else available to rebuild the caliper. Seals, piston, sliding pins are not available as spares!

Oh yeah... and a new caliper is �350!

I already try to apply some leverage between the caliper and the bracket with a big screw driver, but didnt want to push much to not bend the sliding pins. Will try to put some more wd40 in the pins.

Thanks

most lightly it's going to be the front pin thats seized..
The rear pin fits in a rubber sleeve...
On the front pin pull the little rubber boot/seal off "it's toast anyway
& will need replaceing" Then get a spanner & see if you can turn the pin
to brake it free... It should be screwed into the caliper..
Replace both rubbers...
