FFFFFFFFFFUUUUUUU Brakes!

[Paris2]

Aaaarrgggggghhhhhhhhh

So, im trying to change my rear brake pads on the SV (famous tokico annoyance ensues).

The pins and rear pads come out perfectly, so I instantly feel like a smug bastard, "this is going to be eaassssay".

To fit the new pads in I need to push the pistons back, as they are double the thickness of the worn ones. But the pistons don't want to budge, after about 30 mins of shouting and pushing with all kinds of fingers, tools and swear words they move a few mm. I have of course taken the top off of the master cyclinder.

So I gave up and started to put the old ones back in as the rain was getting heavier. I noticed that I could quite clearly see the seals poking out from the pistons:

And to top it off whilst I was wheeling it back down my driveway the rear was sticking making it very hard to move. FFFFFFUUUUU brakes!

So Im thinking its time to strip-rebuild-replace seals.
I need the bike to get to work, is there a quick fix or is rebuilding my only option?

I would pop that piston out and clean. Bit of luck your seal is in one pice. Stick it back togeather and use until your new seal kit arrive.

Would ejecting the piston require a full system bleed?

Just to ease any worries, having never done it before I rebuilt my cbr front callipers in less than 6 hours including a good cleaning and 2 hours spent visiting local workshops to remove a stuck piston.

Cheers all.

To be honest I have been putting off stripping and rebuilding all three of my calipers for a while, as they all need doing after a hard winter.

I will have to order all the seals and bleeding kit and set aside a day this weekend. Looks like the push bike is coming out for the 10mile trip to work

If you want it to tide you over till the weekend, push the piston out a bit (not all the way), clean it, smear some red rubber grease round it then push it back into the caliper with a G clamp.

I think Ill leave the bike alone till I have sorted this, don't want to push my luck with the pistons seizing up and the brake sticking.

Anyone got any recommendations on a brake bleeding kit?

Careful with the bleed nipple though might I add.
I know yours has been quite a sufferer to corrosion from this weather we've had, and my first SV, the now streetfighter project one, used to live in a garage.
Thats just to make the point that when we bled the brakes, with a caliper which was in pretty good nick, the nipple snapped in the caliper and ended up needing a whole new one, unless of course, you'd be able to find the man to drill the old one out .
And this was a bike which was regularly (overly, it's me) cleaned and lived in a garage.
Just be most careful on the re-bleed.

As for kits, Halfords have 'em, I always look thinking, I could do with one of those, but really all you need to do it is a rubber hose (clear preferably, or a jar, and a syringe; did the Hornet at the weekend )

I might give you a call if I get stuck Mike

What diameter tubing do I need, googling seems to bring up mixed results.
