Brake overhaul

So as well as the swinger swop that I'm currently in the middle of (and tearing my hair out over) I'm also busy stripping and overhauling the front and rear callipers, clean up, new pads that sort of thing. All has gone well with this part of the overhaul, the seals and pistons were all in excellent condition so gave um a good clean and put the callipers back together.

Right, stage two new front master cylinder!!!!! Had a scout around and decided that up-rated callipers and braided lines deserved a radial master cylinder........so I got myself a set of Accossato radial brake & clutch mc's

crummy phone pics don't do them justice.......

Clutch

Fitting them was pretty straight forward, obviously all the line fittings come out from underneath the mc and on the brake side you need to also squeeze in the pressure switch for the brake lights, but it all fits nicely even with a two line set-up.

The clutch mc was a bit of a faff as the standard clutch line isn't long enough so I'll need to order a braided one (oh well at least it will match the brake lines now) The cold start lever is attached to the old clutch mc as well, but I got it to seat between the clutch line banjo and the body of the mc, so it holds firm when operated.

All in all very pleased, yet to road test as I have no back wheel, but the front brake bled up easy enough and feels really firm and I’ll do the clutch when I get a new line for it. I’ll be sure to report back in when I’ve tested um.

ha ha....no, it's just a truly random selection of numbers made famous in the 1993 hit song by The Connells........ Sad or what!!!!!!!

Back on thread......does anyone know why the clutch mc has a mirco switch on it????????? and do I need to replace it?

which radial mc's did you go for? I bet you went Brembo RCS's

Any ideas on the clutch miro switch?

Got my master cylinders from Cheesy as he's had to give up riding due to ongoing problems with his knees.
The brake is one of those brembo racing jobs (which means I can't fit the fancy aftermarket levers I've got .... well not on the brake side) and I think the clutch is just the standard RSVR1000 jobbie.

If I remember correctly, the clutch micro switch is part of the interlock circuit that lets you start it in gear as long as the clutch is pulled in

cheers Andy, so as long as the clutch is always pulled in to start (which I always do anyway) I should be able to live without the clutch mirco switch!

No - pulling it in will make no difference - you will have to start it in neutral whether the clutch is engaged or disengaged.
If you do want to fit one, the easiest solution is to get a banjo bolt with an integrated pressure switch

EDIT: just had a look at my (as yet unfitted) master cylinders. The brake has a pressure switch in the double banjo (looks as though you have the same) and I have a micro switch on the clutch.
Both of mine are Brembo - the clutch is the normal one from the later bikes and the brake the super-dooper racing one (not that I was particularly after that - it was just what came up at the time)

BTW last weekend I cleaned up my rotor buttons and the callipers and pistons on my standard Falco brakes. That has firmed them up hugely .... didn't even change the brake fluid or bleed them.
I'm even wondering how the 4-pad callipers / radial master cylinder and braided lines is going to improve on that!

If you get a banjo bolt with a switch make sure it's a good one, but even they don't last too long in my experience. I used to use themon my old GSX front brake and they never lasted more than a couple of years.

Nice work by the way, like the levers a lot.
