Thread: Converting Disco Solid Front Rotors to Vented

this can be a problem.

I have spoken to a couple race teams in the UK - they just recommend solid discs but with good quality Kevlar pads for REAL dirt work.

Kevlar pad would be very expensive, and don't they also have to be very hot to work efficently? If so not really very practical for evey day use, but I could see the use fro them in racing

I have used some pads that were a Kevlar mix in my solid disc Disco.

Worked a treat - hardly any break fade.

I think even Bendix in AU have some Kevlar mixed pads available :?:

Bendix 4WD pads are a kevlar mix, i used to use them on my v8 disco, they were great., amd about to put some on my current unit.

Cheers Dave, thought I may have been dreaming about the Bendix make!!!

guys there is another option .... a mate of mine was telling me that the cross drilled rotors (may) in some applications have problems with stress fracturing between the drillings, he was telling me at the time that V8 supercars ahd gone away from them for this reason (btw i know that im gonna get all these - ive had them and it didnt happen to me)

so anyway he was telling me about these "slotted rotors they dont have the cross drilling just the slots to let the gas out, and they arent so prone to cracking.... but beware the trade off is wearing your pads out quicker as the slot ( on either cross drilled or not) can act as a scraper and take pad off quick...

so there ya have it - oh and BTW I was planning to get the solid slotted rotors , but i might get the spacers and use slotted vented

I've got DBA slotted unvented rotors on my RR and they seem to work well. Haven't driven it much so i cant comment on pad life though.

I now run:
solids on the rear.
slotted vented on front.
Green stuff pads (not cheap)
S/Steel braid brake lines on front (200mm longer than Std.)

have replaced the RR brake booster with a modified one ( sim to rangie spares used to do)

Stops brilliantly.
