Brake discs identification

Post by FrenchNewbie » Fri Oct 26, 2018 10:16 am

Hello,

I need to change my disks, could someone tell me what kind of disks are fitted on my 1977 SE6A ?
And where I could buy new ones for a good price ?
Brake calipers are marked "LOCKHEED".

Thanks !

The "Lockheed" setup has a specific disc unique to the GTE (6a/6b/GTC/Middlebridge) and I'm 99.9% sure will only correctly be available from your favourite trader. SE5/5a/6 (the "Girling" setup) use a TR6 disc, so wider availability (and hence lower price).

Some (Brembo, IIRC) TR6 discs can be machined a little here and there to fit the Lockheed setup - it's a little bit off the outside diameter from memory but it's all dependant on the shape of the inner bell area (hence why I think it's only Brembo ones that are suitable).

Only discs from the club traders fit straight away - you can fit 5a discs if you have the diameter reduced.

You can’t directly fit Girling (TR6) discs with a Lockheed calliper so its a pretty safe bet they’re Lockheed as they should be on a 6a.

As Phil says, Caveat Emptor on the TR6 discs. Some of them will not fit even after machining due to the shape of the bell.

Those discs don`t look too bad?.
Give them a good clean up with a rotary wire brush then flatten the pads by rubbing them down on a sheet of 80 grit wet and dry on a flat surface, but be careful not to breath in the dust.
A bit of work will save you hundreds ££££

I am having a clearout and I have a few sets of Lockheed discs at £120 per pair ??.
I also have a few sets of brake pads at £20 with the wear leads or without.

I have rear brake shoes at £20 per set.

And Handbrake cables for the Lockheed brakes, but they will also fit the earlier Girling setup.

I keep lots of parts if anyone needs a particular part.

Inc NEW master cylinders Etc Etc Etc.

Philippe, as Mark says the discs don't look too bad if you clean them up.
But if you decide to buy new I can recommend his service, rapid and much cheaper than QRG !

Indeed, they don't look bad but they are twisted (I don't know the appropriate word in english, sorry).
The steering wheel vibrates when braking.
Not a tires / wheel balancing issue.
