For what it's worth, my Mantis has a dual-circuit braking system using the reservoir from the TR6.

Hi Paul,

Wow, I guess Marcos just has a thing for single reservoir master cylinders. That\u2019s just odd!

I wonder if they put those on the newer cars as well?

Regarding the POR15, please let us know how this works on the chassis. I have thought about doing the exact same thing to the rusty bits on mine, but haven\u2019;t gotten around to it yet. (Another of those future projects!)

Hi Jeff,

When I had my car prepared for shipping to Canada back in 1976, the car was retrofitted with a dual brake master cylinder and lines to comply with Canadian specs. It was much bigger than the clutch one. If I recall correctly, the front left brake was paired with the rear right, and the front right with the rear left. Following the complete factory rebuild in 1981 due to the fire in late 1978, the dual system was replaced by a single system for some reason, which I didn't notice until the car was back in Canada and it was too late to have it corrected. However the single brake master cylinder is still significantly larger than the clutch one, and the tremendous braking performance was unaffected.

On another subject, I was crawling under my car last weekend checking things out after reinstalling the engine and gearbox following an overdrive rebuild, and noticed that a few areas of the dreaded rust had appeared under the sills on the bottom members, a little further forward behind the front wheel and in front of the rear wheel. Knowing how much effort is required to replace rusted out members, I intend taking corrective action as soon as I can find the time. However, thinking ahead to preempt problems in this area, I came across a paint called POR15 a few years ago that was advertised as rust inhibiting and durable, so durable in fact that it was said that it could be hit with a hammer without the paint chipping off. I thought I'd try it out on the badly rusting post and frame that supports my 10' satelite dish. I used a wire disc attachment for my electric drill to removed the surface rust and then gave it one coat of the paint. After 3 years of exposure to rain, snow and ice, the finish has not deteriorated, so I feel very confident that the paint will work very well on my chassis. In fact it states on the can that it is ideal as car chassis paint. If anyone intends to try it, you should take care to purchase the version that is not sensitive to ultra violet light. The one I have dries to a semigloss black, though I think it is now available in other colours. It isn't cheap at CAN$56 a litre but it does a great job.

Regards,

Hi All,

While the subject of brakes is still fresh in our minds, I have a burning question.

Does everyone have a single reservoir master cylinder for their brakes?

If so, is it bigger or the same size as the clutch master cylinder.

If not, please describe what you have. I will be rebuilding my brake system in the future and would love to put a dual reservoir master cylinder in place of the single unit.

Oh\u2026 and does anyone know what applications (GT6, MG, etc.) the master cylinders came from?

Any info is much appreciated!

Jeff

Mark,

I looked in my spares and all I have is 7/8" and 1" rubber seals. My
rear brake cylinders are 3/4" also. Any foreign auto parts store
should have Girling kits. I ended up getting Volvo kits at the local
shop. Just have them look up brake kits and get a 3/4" one. The
seals are all about the same. I used a brake master cylinder 3/4"
seal to replace my clutch slave cylinder seal?!

Good luck! Hope you can make Davis show on Saturday.
