Mintex m1144 all day. You'll get people on here tell you 7.5 are fine with standard pads , and they are amazing - living in the dark ages.

Not living in the dark ages, just not having any issues with them. Also it depends on what you doing with the car.

 

When i fit my new engine i will upgrade the pads but my original 998 the pads were more than good enough.

 

Each to their own.

 

I can only think that it's the EBC Ultimax pads causing the problem.  Looks like I need to try an alternative.

 

So these are the EBC pads I have which came with the disc brake conversion kit, these are the Mintex 1144 pads which are highly recommended by quite a few people and then there's also these Mintex pads which absx2 uses and are possibly OEM pads.  There's also these Rover Xparts pads to consider.  So much choice!

 

Ebc Ulitmax, ie black stuff, 3 hard stomps and their dead, no front brakes, ridiculous. Had them on a day, wanted to take them back to be honest. Green stuffs aren't much better imo. 

 

Love this forum.. reminds me why its thriving.. :lol:  from experience, doesn't matter if you had a 998 or 1380, it depends how you drive . 70mph is 70mph not matter the power. 

 

 

On a blast over the dales this year, me and mate had a good spirited drive, me 1380, him 50ish 1275, I had brakes at the end (m1144), mate had to stop as he killed standard pads, same type fluid, pace etc. My opinion.. M1144. 

 

From the op, brake fade, think you'd get on well with freshly bled system, decent fluid and 1144's, mintex over ebc imo (yes my opinion).

I liked EBC red pads but can’t find them anymore. Hated EBC green stuff-expensive, dirty and not suited for daily use. Track days and hair-on-fire style of driving, OK. I switched to ceramic pads by TRW and like them.

Mintex 1144 are very good indeed and the vast majority of owners would never manage to fade them. For really aggresive use they can fade as they have done on my 'S', which has 7.5" discs, of course, but I have switched to the Carbon-Metallic ones as sold by Mini Spared. they are simply fantastic and work well from cold.
I have never managed to fade them, although I do use AP600 brake fluid (or its equivalent). The only risk with a C-M pad is that DOT4 brake fluid will boil before the pads fade. I have seen my discs literally glowing red after a special stage, but no fade at all.


Ceramic metallic pads from Mini Spares? Would you have part number? Spares’ description for Mintex 1144 says for competition only. Comment would be appreciated. Thanks

Edit;  Found them, saw the price...never mind!

The disclaimer is to do with ECE Regulation 90. As long as the car was produced before 1998 then Reg 90 would not apply.

I use these....

http://www.minispare...MS.aspx|Back to

With no issues but it sounds like you need Mintex 1144 if you are going to be heavy on the brakes a lot.

I`ve been ripped off by EBC in the past on cars and bikes, don`t believe the hype.

So are they standard replacement OEM type Mintex pads?

 

I don't think I was particularly heavy on the brakes.  Surely they should cope with one heavy stop.  If I was doing a heavy stop like that every thirty seconds I could understand the brakes fading after a few goes but after one stop?

 

They are AP OEM pads, I have the same wheels and no shrouds and don`t have any issues BUT we all have different driving styles and in your instance I would go for the Mintex 1144 without doubt but being non servo you will notice that you will have to press the pedal a little harder from stone cold but not as bad as Greenstuff that are dead from cold, EBC are crap !

I have used carbon metallic pads in the past and they are excellent with instant bite from stone cold but the price £££

M1144 are ideal for road use. You may ignore the statement about suitability for road use. 

Carbon-Metallics are simply fantastic. Part number is:   C-8G8993

I went for a spirited drive today - brakes were fine.  They have been fine except for that one occasion where I braked really hard just to test them.  I must have taken the pads out of their operating temperature range when that happened.  So it's tempting to say the pads are fine but if I do have to do a proper hard stop I'll lose the brakes for while afterwards so that's no use.  I brake harder than many people but not like you would when rallying or racing - I have never had this problem with any other car with disc brakes.  I think carbon metallic pads would be overkill and the 1144s may be more than I need to so I may try the standard Mintex pads which Minispares supply next and see what happens.  Probably be a while though but I'll report back with the results in due course.

Cooper S brake conversion - which rear wheel cylinder?

Hi Folks - I know this is an old thread - but I am also fitting a Cooper S disc kit from Mini Spares to my Mk3 mini - along with the Cooper S master cylinder (no servo) and the 21A1774 brake pressure regulator (rear subframe mount) as part of a single line system. It’s not a Cooper S, but I am trying to emulate a full mk3 Cooper S braking system, on 10” x 4.5 alloy wheels and 165 tyres. My question is which rear wheel cylinders should I be using? I have a pair of the GWC1101, but not sure this is correct?

Yes, that's the correct rear wheel cylinder.
