as above i removed my front wheels the other day and one of my ap discs has cracked
where is the cheapest place for replacement discs they are 315mm i think??

 

who did u get the brakes/discs off in the first place..???.....try Chris Flint at southend carnoisseur.....01702 482545

 

Got mine from Mike R

 

get them direct.

 

Cheap second hand discs on ebay at the moment. I think I would buy a new set though to be honest.

btt for jp

 

Any disc will crack given enough heat, but micro cracks are nothing to worry about anyway, obviously if more, do worry!!
You can help them a lot by cryongenic freezing of them first, not many places do it but there is a place in Stowmarket, Suffolk that does, mkaes a world of difference, used on rally stuff(?) but defo on all engine components used in Nascar etc.

tabetha this is a big open crack mate so its fooked really

 

What PCD - 203.7? What width - 28mm?

At a guess, are they drilled discs by any chance? If so, replace them with grooved items which will last far longer .

 

not a clue mate i will have to measure. but they were grooved not drilled. i run comp th's i am guessing they have poorer cooling characteristcs than mo's maybe this was what casued this problem, as i have never had it on my other cossies

 

I am surprised at this mate, the way you fly round combe i thought you didnt have any brakes

 

What size comps do you run? Maybe a 330 disc could be used as a direct replacement, it would only require four spacers and you could use your original bells.... I have these discs on the shelf .

 

What pads were you using? .

Martin's offer is a good one (if you have the space) .

 

16s but i am changing to 17s so will have plenty of room for 330s what sort of price are they mate.

 

ferodo ds2500s mate i was thinking 330s or 355s depends on cost really

 

Did this happen on road or track?

 

combe i think mate

 

That will be the problem, the DS2500s are really are fast road pad, so to run them on a high powered car with such small discs would mean that the pads would have over-heated and this would have transferred into the disc, cracking them. You really need to change the pad material to the DS3000 for track use to stop the same thing happening again, and then save the DS2500s for road use .

 

Give me a call and I can give you prices..

 

i (proper) cracked one of mine 335x32mm with 2500's, but on the road...i felt quite proud.....................my pal at the garage said "how the fuck did u crack that"...he laughed and then said..."well it is u....init"..........

 

GREAT i have not long bought them from woodford and i told them i needed pads for a track car and they told me these were what i needed

 

Nightmare Dan, at least you know the cause now though

 

yeah i suppose mate

 

at least you are living up to your sig!! hehe
