Caliper seize!

Rolled out my drive this morning. all seemed fine. coming to a traffic light i throttle off.

start pressing both frint and rear breaks.

Nothing happens. i just keep on rolling.

hafing to release the clutch and let it stall to stop before i run into the lanes of traffic ahead.

manages to get my front breaks to work but the back ones just never sorted themselves out.

this is my work horse and i do alot of hacking of traffic and need that rear break.

if anyone could help that would be great.

Cheers
Perry

Sounds like your calipers need a god service, tooth brush, bake cleaner to clean up the pistons, and then some red rubber grease on the pistons will sort them out

i need new pads too. can anyone recommend a set? any red rubber grease do?

Did the levers just drop through or what? Or did they feel OK but no braking effect.

Wemto for both, would save you looking around

Whatever pads you use I suggest you have a serious word with yourself before even considering riding a bike again if you let the brakes get to that state.

i dont even know what to say back to you yorkie. im sure im not the only one thats had trouble like this?
just happens that some poepl know when to service thir calipers. like yourself i would suppose.

They felp like they where breaking but no effect.

Thanks for the help Mavic

Don't say anything back to me just don't let them get in that state again, as maybe next time you won't be so lucky as to have them fail at low speed. Imagine the trouble it would cause if they failed as you're leaving the motorway at 90mph heading towards the traffic lights at the bottom of the slip road!


So there is pressure at the lever? Have the pads actually worn through down to the metal?

First thing I'd do is touch the discs, are they contaminated with oil or something? Then check the pads, are they worn down to the metal?
Then report back. Even with oil contamination you still get some braking effort just very little, however it should be enough to slow you from the low speed you describe.

my rear calliper sezied due to poor/lack of maintance http://forums.sv650.org/showthread.php?t=146871 ended up buying a hole new rear calliper and carrier off fleabay as one of the mild steel bolts is welded to the alloy carrier. the lesson ive learnt this year is regular cleaning/greassing, more so through winter....

I have about 6mm of pad left from what i can see and the disks feel normal. i had washed the whole bike down yesturday. could this have contributed.

only pads i can find are the HH ones on ebay?
