Brake master cylinder.

[steve-V8s]

The braking system is dual circuit, with a pair of pipes to the rear and a pair to the front.

In the master cylinder is there one piston or two, or one piston with two seals on it ?

[steve-V8s]

Excellent, thank you for that.

Next question, how do you access it ? Had the Griff for around 15 years and the brake master cylinder is probably the only bit I haven't had to attend to, until now.

The pedal goes to the floor, the fluid is not going down and can't see a leak anywhere so have to assume the fluid is simply circulating around inside the cylinder.

Seat out, upside down time I think.

Oh, and put a bit of string on the spanner you use. Its not funny if you drop it.

Bit of string tied to spanner is indeed a top tip.

Are you suggesting that with the Clutch master removed the brake can be accessed via the hole in the wing ?

I may be able to get to the fixings onto the servo but not convinced about all of the pipe unions.

[steve-V8s]

How is the reservoir attached to the cylinder, are there some fixings I can't see or is it just a case of pulling harder ?

[steve-V8s]

As said, it can be removed without taking out the pedal box so that was good advice.

Disconnect the clutch pedal and remove the clutch master, remove the rubber seal around the reservoir and pop it off the cylinder ( having emptied it first with a syringe )then you can get at the fixings and unions, one of which is easier if you pop out the throttle cable grommet.

Now, question is can I get a rebuild kit or do I have to replace it ?
