I'm planning on using integral cylinders for the braking on the Tiger. Its a balance bar setup, and I'm using twin .7's and taking it from there...!

Anyone know where to get caps for Girling cylinders with the float switch built in...?

Also, there is no problem with the mc below the wheel cylinder is there..? I **know** it shouldn't be an issue, but its just nagging me now..!

Cheers

Pete

I found these just today!

I have the same sort of setup as you (twin Wilwood integral master cylinders). otherwise, I beleive Sierra cap will fit, but I haven't tried yet...

No problem with the cylinder resevour below the calipers etc

IIRC standard Ford parts fit

Ford part number is 6174635 (or at least it was through www.edwardsford.co.uk!!!)...

pretty cheap.....

I would be very reluctant to use integral mastercylinders of that pattern on a disc brake hydraulic circuit.

That type of mastercylinder was only used on clutches, even in the days of 4 wheel drum brakes brake mastercylinders always had larger resevoirs.

When manufacturers installed disc brakes they fitted very much larger fluid resevoirs.

Why would it make any difference what braking arrangment you have? surely, the only reason for needing more fluid is if your exisiting fluid leaks out....? If so, then do discs leak more than drums? I would have thought as long as you have a clear run of fluid in your m/c, it doesn't matter how big your resevoir is. That is the point of the low fluid switch!

I was initially wary of built-in reservoirs (even though I went for them)....
Especially when you use the float-switch cap there isn't much room left for spare brake fluid.... but so far (500 miles +) I haven't seen a noticable drop in fluid levels so can't see why it makes any difference (as stated above)....

the fluid only drops when you have a leak
The main reason fluid level falls, is when the pads wear thin and therefor more fluid is in the calipers as the pistons are further out.
The reason for the level indicator is to let you know your pads are wearing thin because fluid is low.

Unlike a drum brake system with disc brakes fluid dosen't need to leak for the level to drop.

Quite a common mode of failure with a disc brake is for the friction material to debond from the backing plate, result is instant loss of pedal which can only be countered by pumping out the piston out until you get metal to metal contact.

I have Wilwood integral reservoir master cylinders on the Striker, and I've always been wary about the tiny capacity of them (and the very poorly fitting caps). I'm very temped to ditch them and fit a proper sized external reservoir.

Why not just fit one of these - problem solved!

I haven't seen those for about 40 years -- they were quite popular in the 1960s
