MG Midget and Sprite Technical - New brake discs.

I need new brake discs. Plain bog standard steel wheel discs.

Leacy on ebay, £30.00 a pair including vat and postage.

38 quid a pair from Sussex inc post.

QH branded on ebay £38.40 a pair inc post.

Are the qh or Sussex going to be any better than Leacy?

Peter May Engineering supply Brembo discs at circa £56.
Alan Anstead

Thanks Alan. But do I need Brembo?

Are the ones I listed as good as the standard ones used to be?

Being tight fisted, I have gone for cheap ones without any actual problems. Although on one disc after it had been fitted for a while there appeared what looked like a seam between two bits of steel. It ran, like a chord across the face of the disc and although it never broke up I did change it.
Those leacy ones look good value if that includes delivery. They are heavy items for the post! I've never had a problem with stuff from leacy.

Having just looked at the ebay adds they all seem to be the round boss style whereas the Peter May Brembo discs are the style with a squarer boss which allows the wheel studs to be changed without having to separate the hub and disc.
David Billington

They are probably all from the same original source.

It's not like Leacy or whoever will have a foundry and be casting their own discs!

Malcolm,

Might be worth verifying if that's the case. A quick search for Brembo midget discs found Moss selling them showing the same squarer boss as the Peter May illustration. A bit more searching finds more examples of the squarer boss discs being Brembo branded.
David Billington

Although he didn't actually say so, I'm guessing Malcolm was referring to all the 'standard' discs mentioned in the first post, rather than the Brembos.

Sorry, I guess I wasn't 100% clear. I was referring more to the nobby-no-brand "plain bog standard steel wheel discs". Whichever supplier they are from and whatever box they come in, they are probably all the same.

But if you are paying the premium for Brembo etc. then yes, I bet they are as advertised and, I hope, of a better specification. Although whether you would actually be able to tell the difference whilst driving is another matter...

Me, I am saving up for some slotted and/or drilled discs because they will look wicked when I am down Tescoz car park on Friday night, innit! :-)

Malc.

Edit: Dave beat me as I got distracted looking for fancy discs for myself! ;-)
Malcolm

I'm pretty sure discs are grey cast iron not steel.
Paul Hollingworth

I just mentioned the advantage of the Brembo squarer boss being that you can change the studs without having to separate the hub from the disc. I've changed studs on both hub styles and if the inner inner race comes off the stubaxle then the it's not an issue but sometimes it separates. Of course in this case the hubs are coming off anyway to change the discs so hopefully the studs would get a good inspection and changed if any are questionable or just changed anyway if unknown history as they're not expensive and while the hub off are easy to change. Agreed the round boss discs from the usual suspects are likely all supplied from a single source.
David Billington

I guess the risk of a cheap one is that they haven't been well balanced. Or balanced at all. And then are they accurately machined enough not to run out and cause a brake pulse?
GuyW

Brake pulse. Good phrase. As it happens, that's why I need new discs. I had a sticky calliper. The disc overheated and warped.

"Me, I am saving up for some slotted and/or drilled discs because they will look wicked when I am down Tescoz car park on Friday night, innit! :-)" 🤣🤣. -- Yes, exactly Malcolm. Lol.

And, brembo, delivered from peter may, are 80 quid. 80 quid vs Leacy 30 quid.

Maybe if I raced, I'd splash the cash on brembo. Actually you do get more metal with brembo. 7.7mm as opposed to 7mm thickness. Maybe mine wouldn't have warped.

But, cheers chaps. Decision made. 30 quid leacy it will be. I can buy two sets, for less than one set of brembo. Lol.
