thompster Posted July 19, 2015 Share Posted July 19, 2015 Evening all,Can anyone ID my front brake pads? There's no obvious writing or marks on them and they squeal badly when anything but hot: Link to comment Share on other sites More sharing options...
SM25T Posted July 19, 2015 Share Posted July 19, 2015 Have you tried a 45-degree chamfer on the leading edge of the friction material and a goodly smear of Copaslip on the rear of the backplates ? Link to comment Share on other sites More sharing options...
thompster Posted July 19, 2015 Author Share Posted July 19, 2015 Funnily enough I chamfered the edges while I had them out but didn't have time to do the other side. maybe next weekend. I'm curious to know what pads they are though. Link to comment Share on other sites More sharing options...
SM25T Posted July 19, 2015 Share Posted July 19, 2015 They look like Mintex M1144 ..... but they do all look the same to me ! Link to comment Share on other sites More sharing options...
SM25T Posted July 19, 2015 Share Posted July 19, 2015 Maybe a different friction material was used previously and the discs are still coated with that material. Perhaps a lot of elbow grease with garnet paper on both faces of each disc ..... or new discs. They are cheap enough if standard discs. Link to comment Share on other sites More sharing options...
thompster Posted July 19, 2015 Author Share Posted July 19, 2015 Thanks SM25... I was thinking about changing to 1144's for the sake of it so it'll save me a few quid if that's what they are. The cold squeal is annoying though.The disks were new quite recently. Coppaslip has never really worked for me but I'll see if chamferring makes a difference. I've seen some 3M anti-squeal backing pads which I might try too. Link to comment Share on other sites More sharing options...
6speedmanual Posted July 19, 2015 Share Posted July 19, 2015 Also can try cleaning surface of pads by drawfiling with a medium file. remove sheen snd embedded contamination. Ceratec is a better lubricant for calipers - does not dry out and no clarty solids build up. Designed for the purpose. Link to comment Share on other sites More sharing options...
Mankee Posted July 20, 2015 Share Posted July 20, 2015 M1144s and I think all of the performance Mintex pads have a groove in the middle of the pad to dissipate heat. I do have some stick-on shims for standard pads somewhere if you want to try them, James? Unused of course! Also, I have a good Mintex pads supplying friend and need some more M1144s myself, but of a different pad shape to standard. Link to comment Share on other sites More sharing options...
thompster Posted July 20, 2015 Author Share Posted July 20, 2015 Interesting - I wasn't sure whether the Spitfire Mintex pads had a groove or not and I can't find a photo of the fronts or backs of them to compare. The squealing when cold makes me thing they're probably a race pad plus they stop very well. It'd still be nice to know exactly what they are though!Mankee - thanks for the offer of the shims, I can pick some up round here to save you a trip to the post office though. I'll try cleaning up the pad face too. Link to comment Share on other sites More sharing options...
Mankee Posted July 20, 2015 Share Posted July 20, 2015 James, it's no trouble at all to nip up to the Post Office. It's only a few minutes walk away and gets me out of the house! These shims have been sat on my shelf in the office for years, so it'd be nice to see them being used. At least I think they are still on the shelf. I'll check in a bit.Just dug out some old pictures of performance pads for standard Triumph calipers. Things may or may not have changed in the past several years:M1144s:http://images59.fotki.com/v684/photos/8/42688/8170069/DSCF1797-vi.jpgM1155s:http://images54.fotki.com/v104/photos/8/42688/8170069/DSCF1794-vi.jpgDS3000s: http://images57.fotki.com/v1613/photos/8/42688/8170069/DSCF1799-vi.jpgI used some Hawk Blue in the early days of Caterham trackdaying, which were very good. DS3000s were also great, but they juddered when they were close to needing replacement and cost a fair whack too. Now, I'm back on M1144s, which suit the weight of my car, the way I brake and how many cobwebs there are in the bank account. Link to comment Share on other sites More sharing options...
thompster Posted July 20, 2015 Author Share Posted July 20, 2015 Thats great, thanks Mankee.. No groove so they're not 1144s. I reckon I'll get myself some new pads (for the sake of it) and if the squealing is reduced that'll be a bonus....Next TD will be late August now so plenty of time to sort them.

Nigel Riches Posted July 22, 2015 Share Posted July 22, 2015 Gentlemen the number 1144 refers to the pad material, the shape and form of the pad is MGB533, nothing to do with the elderly British car. Regards, Nigel. Link to comment Share on other sites More sharing options...
thompster Posted July 22, 2015 Author Share Posted July 22, 2015 Hi Nigel, it was just the compound/make I was trying to work out - everyone raves about 1144's but if I already had them there's no point spending money. Link to comment Share on other sites More sharing options...
