Brake disc choice.

[channella]

Has anybody got any experience of running EBC or Black Diamond brake rotors?

The reason for the question is because the brakes will need doing soon I'm thinking of changing to BD grooved discs (although I need to confirm sizes first) with EBC Yellowstuff pads and upgrading to Goodridge SS braided lines.

Since writing the top half, the size question has become a bit puzzling - just what size are the front and rear discs? The difference looks much bigger than 298mm vs 292mm.

edit: Added second bit!

I have been running EBC greens and a set of drilled disks from Porscheshop for the last 3.5 years no probs. Good on the street and track. []

SS braided lines - "Bling" [&:]

Bling. Only a little bit, John...[]

Besides perhaps I've been pursuaded by a tiny technical argument, something or other about line expansion under braking.

Anyway, I didn't contribute this time about h******s, and in that spirit I reserve my right to spend a bit of hard-earned on "bling" brake lines - although don't they have to be visible to someone other than ground living creatures less than 10cm tall to count?

Thanks for the input on discs by the way!

For anyone who's interested for the 2.7 Boxster rotor diameters are:

Front ~299mm
Rear ~290mm

I found some of the website search engines quote "S" disc dimensions for the Boxster. The 2.7 uses the same sized discs as the 2.5 it transpires - well according to local OPC anyway.

Good news is this seems to open up some other options if you want to try something different.

No probs but....seriously - I've never heard of anyone having issues with brake lines at trackdays. (Not yet anyway.) [8D]

I have heard some bad reports about the EBC brake discs before so I would avoid those. I'd go with Brembo Max grooved discs. Really good and look good too. I use EBC Green Stuff pads on a few cars and I can't say enough good things about them. They work perfectly for day to day driving but are still brilliant on the track with no fade to speak of. And they give off much less brake dust then normal pads.
I think the Yellow Stuff pads are for Track only so be careful if yours is a road car.
BF Goodridge Braided lines are a very worth while mod if you go on the track because with heavy brake use the normal rubber lines will expand and you lose a little brake power but a good bit of 'feel'.

Consulted with a couple of independents, and so far the advice - which is consistent - is Pagid pads, standard discs (which we know are Brembo anyway), but maybe change to a higher boiling point brake fluid. Pagid do a slightly higher operating temp pad than standard, but it will eat discs faster. Braided lines improve response but deaden feel, so abandoning that for now.

I have run Padgid Blues on a Boxster S. With Dot 5 brake fluid. They ran so hot I melted the breakpad wear sensors ! ( Ran them for 30'000kms )
So my dash board looked like a disco, with the pad wear light glowing red in my face night and day. ( you can cut them off and check wear the old fashioned way visually )
This happened on two occassions. Both times on spirited blasts over mountain roads. On the track though, Blues are fantastic and fade free. Lap after lap.
After the second melt down, I reverted back to factory fit pads and fluid.
I preferr that the standard brakes start to fade alittle and warn me to back off and chill out for a while.
You do loose a degree of sensitivity with the blues untill you get them very hot.
I didn't notice this untill I switched back to OE pads and now enjoy keeping things smoother and not having to be so agressive in my every day driving just to keep the pads up to temperature..
If you are going to do a lot of track work, Blues are fantastic, but for allround feel and bite the OE pads imho win hands down. How much track work will you do, is the big issue!

On a Subaru Forester Turbo S. I run ECB discs and ECB Green stuff pads. Pads are great, clean and good bite. But the discs make a constant feathering noise . You can can only hear this with the windows down ,when the sound rebounds off walls etc, but for an anorak like me it p....s me off alittle, as I'm sure passers bye in the street expect to see a milk float or something similar drive bye!
In fairness to the guys at power stop brakes. They did offer to replace the front discs but as I live overseas it was just to much of a hassle to take the car to Subaru get them removed,courier,wait, blar, blar ,blar!
Cheers Richard.
