Im trying to refrain from sounding like a broken record, but ebc dont have a good history regarding delaminating from the back plate.

I've used EBC in the past. Superior to stock/ value pads though admittedly not the best you can get. The biggest benefit is reduced brake dust.

 

Delaminating is a scary surprise. A quick search found this thread highlighting a supposed change in EBC's manufacturing techniques circa 2014. I'd be surprised if this is still an issue years later.

Okay, I guess you lot talked me out of it. I'll guess I'll get the EBC pads and the slotted discs as a compromise unless anyone suggests otherwise?

 

Your money, your car.

Sometimes there are cheaper options available, buy you end up spending more just to get the kit you have your heart set on.

 

FWIW £480 for ali calipers and a set of discs would be a billy bargain if you were buying them for any other car out there.

 

 

this really. I'm getting the cooper ones for mine as I like them and its something ive budgeted for.£480 is good value when put in context.

Mine delaminated in 2016 (fitted them 2015) almost causing a life altering car crash. EBC didn't care, still don't care, and have blamed my driving to the cause of the pads deterioration.

Goodness! Was it only used on the road or also on the track? Did the rear drums compensate during the failure?

I once did an international historic rally in Belgium. It was all very fast and on tarmac, so the brakes (7.5" for the Cooper 'S') did a LOT of work. One of the other Minis had EBC pads and I had Ferodo. He actually ran out of pads due to high wear rate and they were not working as well as mine. I had to retire when a new front wheel came off at about 70 mph on a long special stage (not the fault of my service crew, but that's another story), so I gave my the other Mini crew my spare set of Ferodos. They were just so much better and he got a really good overall and class result. 

Now the equivalent Mintex or the Ferodo 3000 pads are great, but the carbon-metallic ones from Mini Spares are even better.

I don't think you can get C-M pads for the 8.4" discs, but Mintex 1144, 1166 or 1177 are superb. Use M1177 for rallying or racing applications. M1144 is fine for the road or short distance competition like hill climbs.

EBC clearly state that Greenstuff pads are meant for road use only. If they delaminated in normal road driving, then that's cause for concern.

I whacked it in 1st and dropped the clutch. It was the only thing that stopped me going into the car in front and spinning out.

 

I've given up with them, i've faught as much as I want to. I put them in 'Steve220's list of crap companies'.

500 odd is not terribly expensive for what is on offer. Decided not to go for it as the stock braking system is good enough for a carefully driven road car. Used the money saved to get the ultra rare Rover toolbox instead. Couldn't be happier!

It is possible to 'over-brake' a road car. Vented discs and multi-pot callipers with larger pads can cause the pads to fail to get to their optimum operating temperature.

A disc brake running too cool can be as bad as one running to hot.

The standard discs are completely adequate for normal 'brisk' road driving. It has to be said that if someone is going to drive so quickly on the road that standard brakes are inadequate then it won't be long before that driver loses his/her licence. for dangerous driving.

An improved pad is the way to go for improvement of road use pads. The Mintex range seems to be the best or, for the 7.5"discs, the Carbon-Metallic ones from Mini Spares. M1144 for nrmal road use, the M1166 for club competition use and the M1177 for full-on rallying or racing. With the 1166 and 1177 it is best to use a competition brake fluid (AP600 or equivalent).

A few hundred miles later the 8.4 Minisport discs with EBC pads appear to be doing alright. I’m hyper paranoid of delamination now, and check the brakes often.

That being said, I can’t say that I’ve noticed an improvement in everyday braking other than a sharper bite during a very hard stop.
