Shaun, you are very bad man. So far I have resisted your wares but you are wearing me down.

Really frustrating the past few weeks but at least finished overhaulling the calipers.

Coated in gloss black, new seals, stainless steel pistons and Redstuff pads.

Just need to finish the rest of the car.

Had a couple of close calls with cars behind, so keen to have a third brake light. However, I do not want a permanent fit. Adapted a US spec Jaguar XJS light and added some strong magnets so it can be a temporary fit.

Trial fitted the dual circuit late model MGB pedal box with a dual diaphragm booster.

A really tight fit but like with all modifications there are flow on effects. Need to make a bracket for both remote reservoirs and the bonnet prop rod fouls on the booster when the bonnet is closed.

James,

I wonder how that would look on a GT just forward of the hatch lip? Is it flat or curved on the bottom?

Thanks,
Bil

It is flat on the bottom. However, there is a rubber gasket, that will allow for some slight curvature.

That is a nice looking master cylinder package. I like that it incorporates the proportioning valve and pressure switch all together.

What is the pedal ratio and the boost ratio?

Ken

The numbers I wrote down somewhere for the pedal ratio but it's very similar to the original pedal. Going by memory I think the original pedal was about 3.08:1 whereas the MGB pedal was about 3.48:1, but don't hold me to those numbers.
The booster ratio isn't recorded but it would be very similar to the original 8" booster that was fitted to the car.

I was very keen not to create a situation where I overboosted the brakes and locked up everywhere. The master cylinder bore is slightly larger than original at 1" and combined with the Redstuff pads and sticky tyres I think there will be an improvement.

Hi John,

Won't a larger master cylinder bore give you less braking power?

I would think that for a given braking effort (leg pressure on the brake pedal) a larger MC bore would give you less psi brake pressure output from the master cylinder.

Ken,

A large bore will give you more fluid but less fluid pressure, whereas a smaller bore will give you less fluid but more fluid pressure. If you use a small bore with a large caliper piston, like the MGC has, you get a soft pedal, so you will be correct but by how much I'll have to wait and see.

Although I would've preferred the standard size 7/8" bore I couldn't find one that fitted the stud spacing the only 7" dual diaphragm booster I could get my hands on locally, so I'll have to take my chances and hope I haven't miscalculated too much.
