Brake dust seal has come out....Bugger

No. And clamping the rubber hose off with a set of mole grips keeps mess to a minimum.

Sorry I just notice you posted while I was posting That makes things a little nicer

It's not a bad time to change the fluid, mind.

How often should it be changed?

I if do replace it do I just drain it all from the bleeder valve?

Every 2 years.

TBH I would change the fluid. Since you are overhaulling the brakes, then brand new fluid is only a couple of quid extra so why not.

Yep I pumed it out of the bleeder valve. Just remember to tie some old T-shirts or rags around your paint work as it is easily bugger-up-able!

I always have a hose or bucket of water standing by

Well I can't seem to find red rubber grease anywhere locally so I have orderd from Frost, I wonder if I will get mine wrapped in the Daily sport or not

I am also going to change the fluid while I do the breaks waits for Viney

Ok I was in for a pleasant surprise when I got to the dealers, they thought there was only a dust seal and piston seal per pack but there is in fact two so only around £25

I am currently trying to get all the brake fluid out of the callipers. I have put a tube on the bleed valve and took the top of the reservoir and pumped the leaver which got most of it out but there is still a bit in the calliper that came part way down the tube them went back into the calliper and I won't come out if I pump the lever. What do i do to get that out? Or do I just take the calliper off with it in?

pop the caliper off anyway, put a small plasrtic bag or similar round the bottom of the hose to keep the mess down. Anything that's left in the system will be replaced when you add the new fluid anyway

Ok I didn't word my last post well. In a rush to go out plus I hate typing .

When I said 'No' that was because you need the pressure in the system to get the pistons out. Once the pistons are out , the fluid will be drained ie two bird with one stone

If you unbolt the calipers now you'll more than likely have a bi*ch of a job getting them out. As the piston are forced out you need to top up the reservoir to stop air entering.

Don't take the calipers off unless you have compressed air to force the pistons out.
The other option if the calipers are have been taken off is to use a pair of mole grips. Put cardboard inbetween the jaws to protect the pistons to try and pull them out. Even with protecting the piston surface you may end up marking them.

PS: With regards to getting the pistons out , hope don't sound like I'm trying to show you how to suck eggs
