Front Discs and Pads.....Anything to look out for?

[Flat 6]

Johnny Holland recommended Porterfield Pads which I used to use for trackdays in an old Sc. They were fantastic and because I couldn't be arsed changing them after a long day at Anglesey, I found out they were perfectly fine for general road use.

He also recommends sebro disks.

I've ordered Sebro Discs and a set of Brembo Pads.

I've also ordered a set of EBC 'Green' Pads but will check out some reviews before fitting them. Apparently theyre great when hot but poor from cold

my experience of EBC pads (Porsche 964) are they heavily powder coat the backing plates, so they look great but they don't really fit very well without grinding it all off the edges! this is from 15yrs ago so things may have changed since then, but they royally screwed me over when I complained, so once bitten twice shy..

Brembo standard pads are just rebadged Pagids. The HP Sport are different

Green Stuff, Red Stuff, Yellow Stuff etc - all turn rapidly into a different colour stuff very quickly.

We recently had a car suffering from a long pedal. It had a new master cylinder, new hoses, calipers rebuilt and none of these changes improved the pedal.

We tried the trick of 'exercising' the pistons and the pedal stayed long.

We changed the pads from Green Stuff to Ferodo DS2500 and the pedal improved significantly.

We tested the pads - crudely - by installing them in a vice with thin aluminium sheet to protect the friction face and the amount by which the pad compressed elastically was amazing.

An ATE pad compressed by around 10 degrees of vice handle rotation and the Green Stuff by almost 180 degrees.

I did try them on a Lotus Seven around 10 years ago and the pedal in this car had a similar feel to treading on a dead cat.

Changed them after 1/2 a day.

The advertising of some pads has become confusing.

EBC pads and many other manufacturers supply pads which are said to conform to ECE R90 Standards.

ECE R90 requires that the friction coefficient of the brake pad must be within 15% of the standard pads homologated for the vehicle.

This is to ensure that changes of pad do not significantly influence the pedal force needed for a given deceleration and other aspects of general braking behaviour.

There are also measurements of hot and cold fade resistance, compressibility and a range of other characteristics.

Ferodo DS2500, DS3000 and most of the Pagid Race pads are generally NOT compliant with ECE R90 because they provide too high a level of friction compared to a standard pad.

without fail, always learn something when you post!

I’ve run Ferodo DS3000 and DS3000 on my SC (running 3.2 Carrera calipers and discs).

DS3000 had mega bite and performance but we’re far too dusty for anything other than track use. They also eat discs for breakfast. The DS2500 don’t have quite the same initial bite but they have provided great performance and seem friendlier to discs. My car is mainly fast road use now and they are great hot/cold winter and summer. I’ve just bought a full set from circuit supplies ~£150 inc VAT
