Which PF pads for S2?

[Neil Haughey]

Guys being looking at getting some from a motorsport parts supplier I have used before in the states, very good pricing and last time they got parts to me in 3 days flat (UPS sooo much better then parcelforce etc) from when I punched it in on their website.

AFAIK the S2 and similar turbo calipers will be using the 345 pattern, the PF website lists 2 different types a carbon metallic one and a Z rated.

Guys firstly have I got the pattern correct? and which type do you use? ISTR they used to say 97, 01 etc.

 

[Neil Haughey]

Also am I correct in thinking that it is the same required front and rear?

 

[Diver944]

Yes the S2 has the same size pads front and rear and Performance Friction call them pattern 345. You can double check by measuring the pad which should be 96x48mm

However the two types you mention (Carbon Metallic and Z-rated) are part of their road range. The track pad of choice is PF97 from their Motorsport range. It's billed as a longlife pad which is gentle on disks and works perfectly from cold.

 

[Neil Haughey]

Cheers Paul, ISTR PF97 is the one in me catalogue in that pattern for something like 100 bucks an axle.

I want to fit the same pads front and rear because firstly the workshop manual says you should and secondly I believe my oversteer on the brakes that I suffered at Bedford last year is caused by having stock pads on the rear and these good but expensive BHP XPS pads on the front.

I have had amazingly good service from these guys.

 

[Diver944]

Yep they are the ones, and that is an amazing price for the slightly smaller S2 pads - equivalent to £50 an axle before vat and import []

The 250 Turbo front pads are $300 +vat and import from the same place, I was lucky and a friend brought some back in hand luggage for £120 last year

 

[Neil Haughey]

After all that I remembered I have some unused credit with Pelican parts so I have ordered another set of BHP XPS pads to fit on the rears, oh well may be a little longer before I try the PF pads.

 

[appletonn]

So which size PF pads do i need for my '91 Turbo with the medium black calipers?

Also, would their road range pads be OK for ocasional track use, ie better than stock pads but without the tendency to destroy wheels that the PF97 pads apparently have?

I finally plumped for some Porterfield pads following some advice from someone who has prepared more than a few race & trackday cars in his time and who swears by the Porterfields to give squeal-free road performance from cold but which will take the heat of a trackday.

I will post my thoughts once I have bedded them in.

I'm hoping that some fresh Dot5 fluid and Goodridge hoses all round will give me the firm pedal I need!

Cheers

I'm sure you'll love the Porterfields, I think they're fantastic. You must follow the bedding in procedure to the letter as otherwise they will fade and feel soft, but once that's done they're perfect. They will squeal however, they tend to glaze up with road use (a couple of hunred miles I guess), it doesn't seem to affect performance but makes them noisy. A dry track day will soon have them quiet again. The pedal should be very firm with these pads. I look forward to hearing how you get on.

 

[appletonn]

Thanks Peter, will do.

Is your car a pure track car, or do you use it every day?

Must be pretty light?

 

[Peter Empson]

It's my only car, so it's used daily and does circa 10K per year. When it's painted I will finally get it weighed, but by track car standards it'll still be pretty weighty as I've left in some creature comforts. I would be delighted if it were in the high 1200's but suspect it'll be a portly low 1300's with the half cage and super charging paraphernalia. There's not much more weight to come out now either []

ISTR must use DoT 4 fluid in the 944 brake system. Most ppl tend to use something like ATE Blue.

 

[sawood12]

I use ATE but am not sure if it is DOT 4 or 5, i'll have to check. However there are people using Castrol SRF with no probs which must be a DOT 5 given its price.

 

[944Turbo]

I use dot 5.1 from halfords or castrol it is synthetic but not silicon dot 5,

Has anyone here used both the PFC and the Pagid Blue pad? I'd like to know your impressions?

 

[appletonn]

Yep, my typo - it is ATE Blue going in!

 

[Peter Empson]

Just a word of warning, but I had lots of problems with ATE Blue boiling (and a less than rock hard pedal), so if you have issues I'd look there first. I would now use Castrol Response or SRF as I've had great results with both.

 

[333pg333]

Hmm that's interesting on the ATE blue Peter. I hadn't heard anyone say that yet. Good to know.

 

[sawood12]

Funny you should say that Peter as i've not got a rock hard pedal and have been putting it down to my EBC pads. I might try a fluid change then.

How many litres of a brake fluid do you need to fully flush the system? I got 10 litres of ATE which was way too much.
