brake pistons / pads

[s1h]

Ive been a twat I attempted to change my brake pads and have got in a mess. I got the old ones out then pressed the brake lever and the piston came up. I can't get it back in its not fully out but how do I push it back in it just won't budge

First of all don't go too near the lever for now and don't panic.

Take a toothbrush and clean up the piston you can see using some brake fluid. Then push the piston back in - you may need something to help you - got C clamp or similar? Put the old pad between the piston and the clamp though. Failing that put one of the old pads back in to protect the piston and use a screwdriver to lever it back in.

Then pump the piston out a bit more and clean up the crud again and push back in. This should get it moving more freely and give you space to get the pads in.

Hi

As above. But also wash off all traces of brake fluid from any painted part of the bike (and from the tyres) as soon as possible.

All the best

if you can get one in, hacksaw the piston til the pads fit or cut the brake pipe to relieve the pressure to push the piston back in then join the pipe back up with a biro and jubilee clips-bleed,nah,fuk it, spongy brakes have more feel.

Good news a c clamp did the job applying pressure on one off the old pads.

However what looks like some metal clip or something has now come out any idea what it is and how it fits back in? Does this hold the pads in at the bottom?

Starting to wish I hadn't attempted this now

IIRC the hornet rear brake pads have 1 pad retaining pin.

So the pad spring should just sit in the hole at the top of the calliper (domed side facing out).

The pads should have 2 bits sticking out with on the top, which when pivoted into the calliper, touch the 2 "feet" of the spring and holds them tight.

Cheers. Yeah it doesn't seem to nicely slot in and the pads don't seem to just slot into it. Sure it's something simple dont really want to admit defeat though.

Maybe ill pick up a Haynes, might have some pictures.

Hello people. Finally getting somewhere. Had originally thought the pads had to clip into that spring. Now I've worked out they don't I've cracked it. Well sort of. I've put it all back together but now the rear brake is sticking. It's ok going forward but really sticking if I push the bike backwards.

Any ideas what have I done wrong, something done up to tight. I was thinking maybe I'd pumped the lever too many times as the piston is quite far out?

Is the caliper moving freely on its slider pins?
