Urgent - Bleeding servo brakes

[Packer]

I know that this has probably been done to death but I'm running out of time!

1150GS servo brakes 2003.

I've fitted a replacement front left caliper. I had everything ready to hand so it was a case of quickly disconnect old caliper, switch union to new and do it up again. Probably only lost a tablespoon of fluid.

I'm now trying to bleed the caliper without a vacuum pump. I have a clear hose with a non return valve on the end and just to be sure submerged in brake fluid in a jar.

When I switch on the ignition and pull the brake lever a steady stream of bubbles come from the hose but the level in the handlebar reservoir doesn't seem to be dropping.

Can I just leave it to run?

Is there another reservoir under the tank?

All (sensible) answers appreciated and see you for at East Midlands, if I get finished

The two aren't directly linked Kevan.....

You need the tank off ....there are a couple of places where the fluid is topped up with the relevant pipette type thingy...

Sorry I can't help more, I've never done it myself, just watched the techie at Central over a year ago...

Thanks Mike, while I was waiting for a reply I found a link to another thread.

I'm pretty sure I've emptied the servo so I hope it's not kaput! It was still blowing bubbles so here's hoping!

That's a very useful site.

The Haynes Manual is completely useless for dealing with power assisted ABS brakes

Your confirming the tank removal Mike was all that was needed.

A quick trace of the pipe from the handlebar and to the calipers confirmed which filler I needed to open and that part was plain sailing.

I simply used a small funnel, top up, pull brake lever and repeat process until no bubbles appeared and hey great brakes

Then I remembered that I had brimmed the handlebar reservoir

Tried to get the top off and although I had only nipped the screws up expecting to have to top it more one wouldn't come undone. Bloody cross head screws

I had to loosen the union slightly and squeeze the lever to pump out a bit of fluid.

But at least I have brakes and it's only Tuesdy night It's funny how much smoother and better 8 pistons are than 7.

Slight change of subject, I got hold of a wee stick of aluminium anti seize. Made by Loctite. It's just like a big lip salve tube. Brilliant, easy to use and good for use up to about 900 centigrade. £5.40 or something like that from RS Components but I guess other Loctite stockists would have it as well.
