PF brake discs - are they really any good!?

[_Nathan_]

I'd have thought wear was a function of friction rather than just pad hardness?

Get some temp paint on the new disks, be interested to see what is going on...

as DS3000 prove, the compound of the pad will have a big effect on disc wear, not always the grippiest wears most. One side is always the weaker and my guess is wioth RS14 the pad wears forst and RS29 the disc more

Friction is what is caused by both touching - which wears more or less depends upon their make up

[_Nathan_]

Have you got the friction curve for DS3000? Very high I suspect? Is there a pad that is low in friction yet still wears disks at a very high rate?

I still think RS29 are kinder to disks :P

What he said ^^^ :whistle:

you may be right........

but theefore you are saying the RS29 wears slower and the disc wears slower and it stops the car as well or better - something doesnt add up!

[_Nathan_]

RS29 doesn't stop the car as well - look at the friction graphs! I always thought with RS19 \ RS29 you were trading outright stopping power for disk and pad life.

[shimmy]

yep

just found the Pagid paper that says that RS19/29 were developed from RS14 and "give a reduction in friction level and longer pad and disc life!!"

So my PF discs have done ok then :thumbs::hahaha:

And i was angling for PF to send me some new ones as a trial :banghead:

I may just try then rear RS29 pads next to see how it affects balance, not that i have been having any issues (always been ok at late braking) but will be interesting

:hahaha::thumbs::smt055

your car seems to be very good on pad life

2 years/one set!

PMSL :bigcry:

Give me money and I'll go racing :whistle:

Anyway 2 years ago it was still my daily driver, only been caged for a year and a quarter :birdman:

I'm more than happy with stopping power and longevity of discs/pads using the AP/RS29 combo.

But then i only weigh a third of Shimmy's mass... :whistle: :blalalala:

at the speed you go youd be happy with cheese ( just a splodge of your KY)

:hahaha: :hahaha: I'm more than happy with my speed at Spa - i have no records to try and beat. I also don't love it quite as much as you clearly do!

Come round the Ring with me next time...

[shimmy]

Come round the Ring with me next time...

nah, gotta leave you the King of somewhere









Anyway it scares me too much









And I promised mself and the wife I wouldn't



Ohhh, go on then
