Would it be these? The blurb isn't clear but does mention M1144. Mine are 8.4s

It looks like they are M1144 and that is the marking on the backing plates of the pads in the picture. 

I never know why they are given the 'not for road use' tag, as they meet or exceed the requirements for brake pads, contain no asbestos. but cover a broader temperature range than standard pads. 

I always thought that the only reason pads might be marked as not suitable for road use is because if they did not fade before the brake disc temps were very high, the brake fluid might boil, which would effectively cause brake failure. I was once using the old Ferodo DS11 race pads and boiled the DOT 4 brake fluid. I changed to AP600 fluid, which replaced the old 'Girling Amber'  competition fluid.

M1144 will fade well before DOT 4 will boil, although with M1166 or the C-M pads an AP600 fluid is needed.

For more advice you could call 'Questmead Ltd' in Rochdale who are friction material specialists and can supply what you need for any particular application. They do have a web site.

I have used 1144 pads in road cars and short oval race cars and they perform in both.

Drain and refill with fresh DOT4 fluid (check rear wheel cylinders for perishing/ weeping whilst you are bleeding brakes.)

In addition to this, I have EBC pads on my 1980 Clubman Estate and the dust levels are extreme in under 5k miles. (I fitted a Huddersfield mini spares 7.5 inch disc kit, so pads are what came with this....)

I certainly will be upgrading when I need to.

The dust level on these is very low. Did you mean you'll be upgrading to the M1144s. Daz.

Yes, my apologies, I should have been clearer 👍

So I've bled the brakes tonight and nothing else. Took it for a spin, and once I was somewhere open, straight and quiet, tried some sudden stops. I had a minor pull to the right previously. This wasn't picked up at all for the MOT so minor. That has gone now and the stopping did feel a lot sharper. Maybe I had an imbalance of some sort that reduced the braking power, and contributed to the over heating. I think I'll probably give the M1144s a go in the near future due to the increased heat range. To be continued.....Daz

Good work ....

Am I missing something, as these say “Competition only pads. Not for road use.”
And yours is a road car, so curious why you’d consider them?

Hi Beardy. I did ask that same question early on, but based on the advice and experience of other users that fact doesn't appear to be a
problem. I'm definitely open to more opinions and options though. Daz.

Something I did notice when bleeding. One rear nipple, drivers side, was 1/4 inch fitting, whilst the other was 7mm (I think). Definitely different sizes anyway. Which one is correct on a 93 car, and has one been re-tapped to fit the odd one or are they the same threads and inter changeable?

New cylinders have 7mm bleeders, older ones were 1/4”

Wheel cylinders only last a few years before needing to be replaced, so I’m guessing one or both have been replaced

I've got vehicles with wheel cylinders that have been on for more than 20 years, and the vehicles aren't in regular use, although I did put some rubber grease in to stop them seizing up.

Thanks Timmy.

It's not unheard of to find metric threads on all sorts of stuff that comes with fixings included.

When I put some new green stuff pads in I did the initial bedding in, then on a long downhill section I had all the symptoms of fade: smell, smoke and very poor braking. I stopped at the bottom and let them cool off and they’ve been great ever since then

I had a similar thing with the Black Stuff pads which came with a disc brake conversion kit from Minispares.  Had them on for a few hundred miles and then decided to test them by braking really hard from high speed.  I'd never experienced fade like it.  Five miles of normal driving and they still hadn't regained their stopping power.  I was ready to ditch them for 1144s however after letting them cool down they worked fine again and I've never experienced fade from them since then thousands of miles later.
