Back brake absolultely knackered after trackdays

[Paul the 6th]

Cadwell on tuesday 17th Aug and then RAF leeming last saturday were asbolutely ace - but now my back brake isn't working..

You can push the lever all the way down to the stop - the pad does connect with the disc but the bike gently rolls to a stop.

It's still got original rubber brake lines and has had the same brake fluid & rear pad in it since before I got the bike (I've done 7,500 miles since march) but it was working until the end of saturday when I got home..

So what do we reckon has caused it to fail? Has the brake fluid boiled on track day, then expanded, and now that it has cooled it's left space to expand into? Or has the brake line expanded from the heat maybe? Or could it be the rear pad has thinned right down to the point where there's nothing left?

Guesses on a postcard as I'm off to fix it today :D

PS, just bleed them. Sounds like the fluid in there has boiled and given off gas.

you use the back brake on trackdays!!!??? I've only ever used it at Cadwell over the mountain and a little bit where there's that horrible crest on the back section of Oulton. Certainly not enough to cook the pads though. It sounds like it's just boiled - bleed it and it should be fine. Are they braided lines or standard?

only thing my back brake does is keep the scrutineers happy

you'll see on the RAF leeming vid there's a bit where I run into a corner too hot - if my back brake had been working properly I reckon it would have just about scrubbed enough speed to stop me running 2 ft onto the wet grass...

Tis nice to shave some speed of gently sometimes - me and irksy dan both do it, and there's nothing gay about it thank you very much.. (love you dan xx)

Irksy dan who fell off from losing back tyre at last one? :-P

Nothing to do with rear brake... you were distracted by my sexy leathers.

[Paul the 6th]

apparently that was due to a squared off tyre? :razz: those comedy 90's leathers did actually dazzle me a bit, hence why I tried a bit of motorcross over wet grass on sticky touring tyres :)

+1! I have rear race pads and a wavy rear disc that have never been used :)

But then I missed a gear and proved that the SV can indeed rev to 13,000 rpm.

I sharn't (a much under used word) be doing that again soon!

I only remembered my track bike had a back brake when the front ones failed....

I guess it's possible you're been "comfort" dragging it a bit and overheated the fluid, especially if it's fairly old anyway. Change the fluid, give the pistons and surfaces a good clean/lube and check all moves freely, then leave it alone!
