Spongy brakes (front)

[Rossi]

Done all of the above mentioned to Micks brakes.
Fluid has been flushed and replaced. Bled as per normal. Bled from bango fittings. Lever tied back to bars. Lever pumped continuously for over 5 mins with no air appearing in reservoir. Vaccum / suctioned through system.
Still they refuse to give a firm lever.
At this point I am thinking a MC overhaul since everything else has failed to produce results.

Adrian, no good asking Mick (he has as much mechanical knowledge as my dog )
The following had me crying for days as I just couldn't get a decent "feel" to the lever
did you have a look at the metal backing the pad material is attached to ?
I've had one before that was bent, this was causing the disk carrier to be "pulled into shape" before the pads started to bite

Solution is so bloody simple!!!!!!!!!
Mix Viagra with the fluid dumbarses

DOH! Why didn't I think of that, that would surely make it HTFU! Got any spare stock Steve?

So I bought me some CRC brake cleaner today, spose i'll give it a hiding tomororw with the (probably vain) hope I might not have to pull the whole thing apart as i'm bound to lose a bolt or fuck things up somehow.. can't do any harm can I?

All I would do is slide some cardboard or newspaper up between the back of the caliper and the wheel to stop the wheel & tire getting a big blast of brake cleaner. Also take off the anti rattle clip from the back of the caliper so you can get better access, and if you are a bit keener take the calipers off (leave the hoses connected) and pull the pads out to give even better access. When you have used up your brake cleaner, give averytning a good hose off, reassemble and hopefully it has made some difference (for the better).

Mick,

I have recently replaced all the seals in my calipers, I also have a new piston etc for the master cylider but I havent installed that yet.

I noticed a little improvment immediately and it got better as the brakes bedded back in.

I did it with the help of Tim (GPX750R) it wasnt hard you just need tools and some lateral thinking

For some reason the same calipers on the ZRX feel sooo much different

Bring it down Saturday arvo when you come to watch the Geelong/Colliwobbles game on the Bigscreen and I'll fix her up
I know a liitle trick with the seals and have pulled apart many a cylinder.
I stopped mine squeeking easy enough........I just threw it down the road and it don't squeek anymore

MC as you are now looking at...........as wobbles suggested .......have same prob with the 250..............but ever so slowly lose pressure ....so dont really notice till .........oops i'm half way through intersection and my right index finger is crushed......trying to stop at a revenue camera (VIC) is it lack of general maintenance on an old bike (how dare i mick) hence the MC .......we all bleed drain fluids etc over period.....but mc never checked for propper seals
where's that back yard big end mechanic
