Those running uprated front brakes......

Postby simonbuk » Thu 12.10.2017, 10:02

What pads are you using and which do you like ? I've got front HiSpecs which according to paperwork might have Hawk pads in them. They just seem to get very hot, very quickly, and smell quite bad.

They are probably quite old so I was thinking of changing anyway.

Any recommendations ?

I use EBC on both of mine. You can get different compounds dependent on your driving ie fast road, track days etc.... Their current Greenstuffs are far superior to their old type Greenstuffs which needed to be warmed up before they were efficient. Not so good for the first few braking sessions in town and more for track day sessions :burnout:

I had a set of greenstuff (the newer compound) on the rears, but i was not happy with them. After a year the pads de-bonded almost completely ! Dangerous, but perhaps exemplary?
Since upgrading to hi-specs on he front I use Mintex M1144 compound all around. A bit dusty, but performance is good from cold an in my limited experience they feel better then the green stuff.
I have been told that greenstuff compound changes regularly so perhaps my info is old now :D

I have the stock brakes but as for the pads I am using EBC yellow stuff and I am quite happy with those — I read the old yellow stuff used to brake only when warm but the newer compound I have is fine when cold too.
By the way, the rims are quickly dusty, I don't really care but if you do that could be annoying (I think I remember their red stuff is their cleanest compound, but not too sure about that, it's all explained on their website)

Simon - I'm 3 years into my 2-pot hi-spec brakes and just changed to 'green stuff' pads. Although, I must admit, Pete said "no need to use any of the green stuff pads, you don't need em" he was right; I can't tell the difference using these green stuff pads.. the brakes are just the same... fantastic.

I run 264mm x 10mm discs on my rear hubs and use EBC DP197 (Standard Road Pads) in the Ultralite 2 calipers. Don't think the rear brakes ever work hard enough for long enough to justify Greenstuff, even round Castle Combe racetrack.
Fitted early Greenstuff (probably 15 years ago) to OE front calipers of another SE and they were absolutely dreadful cold. Developed the habit of driving 250m out of the village with my left foot on the brake to warm them up before I got to the open road and twisty bits but was still a problem on motorways when I hadn't used the brakes for some time and needed them - that slight delay before they started to bite was a heart-stopper.

My HiSpec Billet 4 calipers on the front came with what look like Redstuff pads that I thought may be a bit hard for general use so bought a set of Greenstuff (DP2143) as members were saying the 'cold problem' had gone but Redstuff are very good so Greenstuff pads are still in the box. May fit them to bed them in so I can compare through the winter.

The best front pads I ever had were Pagid RS4-2's, also known as Pagid blues. They were quite expensive but worth it as, when the OEM calipers were properly fettled, they were every bit as good as the HiSpec set up

We'll have to debate this over a beer one day Mark ... but single pot sliding caliper can never be as good as twin pot, as on my Elan Plus 2, or triple pot as on my Eclat. Agree that when properly fettled the OEM calipers can be much better than on most M100's but they do need constant attention. Single pot sliders are a cheap and cheerful, but fundamentally BAD design that have no place on a performance car - when working really hard torque on the pins will produce resistance to sliding and one pad will work below it's full potential so never as good as a twin pot set up, and the sliding caliper has inertia that relies on disc run out to knock the outer pads away or they constantly rub. Spent this afternoon changing discs on my daughter-in-law's Astra 2.0 Turbo that has 200 bhp, 308mm discs and quite a nice car apart from those bloody single pot calipers :banghead: .. look how uneven the disc wear is ...

Phil - we don't need a beer, I totally agree with your discussion 8) And that's the main reason why we change to Hi Specs, Willwoods, AP racing etc.. set ups. Myself included (Hi Spec's)

But, I would like a beer anyway. See you in the Smoking Dog beer tent. Mine's a Wiltshire IPA :cheers:

Wow, indeed the right disc is much more worn than the left one!!! :lol:
Seriously, that's impressive indeed. Are the sliding shafts working properly or are they a bit seized?
As for the stock brakes maintenance, since I have refurbished them they seem to brake well with no maintenance at all — so far ^^

ha, ha ... Nothing seized, or even stiff, moves freely when pushed hard but it's such a big heavy caliper working on big heavy discs. New discs came in a box of 2 and I nearly got a hernia lifting the box.

another advantage of aftermarket twin pot calipers - aluminium ! Keeps weight down and it's unsprung weight ...
