Finally got chance to get the new 'prototype' front brakes fitted up yesterday.

A reminder of what I had on there previously, Wilwood 4-pots with 247mm vented discs;



And the new ones are a solid disc with an alloy bell (from an OMS single seater) with Yamaha R1 motorcycle 4-pot calipers;

These are the mounting brackets which Sleaford Minis made up for me;











And here they are mounted up on the car;











Total weight saving compared to the Wilwoods is nearly 6.5kg.

I still need to do a bit of fettling on the offside brake installation as something isn't quite square, the caliper body is touching the disc in one place as it passes through a revolution.

I got the pedal box re-installed as well, plus the steering rack, steering column and gear linkage, so there is a little progress.

Looks like a good fit, are they man enough?

I think the bolts will, in time, need replacing with shanked ones, as those threads will chatter to nothing. Unless you do something with chemical metal over the threads to fill the gaps. And the nuts will definitely need replacing with either 2 small thin ones per side, or some metal lockable ones, as the nylock will melt out with hard braking.

Good point Mike, I hadn't considered the bolt needing a shank on it.

As this was just to test whether the brakes are actually going to be adequate, I haven't worried about doing anything fancy yet.

If they work then I will use a 'K' nut in place of the nyloc, and I will have the brackets and the spacers for the disc properly made.

They do need making from a decent bit of solid, ally should do

as for the catching, surely thats the disc/hub running slightly warped, and not the caliper?

I know weight saving is your religion, so when you get proper spacers made up, you could get them tapped & run allen head bolts & loctite instead of the type of arrangement in the pic... I know its only about 20g per side, but it all adds up, as you have proved many times.

Limited progress to report, I pushed it out into the sunshine this morning to get a few pictures of how it currently stands;





















As of last night the engine and gearbox are ready to go back in, with the new flywheel and clutch installed and checked for clearances. I've also fitted a new crank seal whilst it was all apart.

I've given up on trying to fit the fibreglass doors, and the original steel/aluminium doors are now being painted reeady to be re-fitted. With a little bit of effort I managed to get the weight of them down to that of the fibreglass ones anyway!
