Thread: Vented front brake conversion

Get some vented defender calipers, vented rotors and go from there. When you come down have a look at mine on my rangie.
I got my calipers new from the UK for not much money at all

Is there a difference between the defender front rotors and the vented RRC ones?

I'm pretty sure my 91 has vented fronts, can't remember if the rears are, but it would be nice to know if there are bolt-on "upgrades" to improve the braking performance.

Davis Performance Landys sell the spacers.

Rears are solid but some rrc had vented fronts , think it may be the abs models.

AFAIRC there is not a lot of difference in braking performance between solid and vented, stock RRC or def caliper conversion. The def caliper conversion will obviously give better braking performance over RRC, but vented and solid are available for def and RRC, if you get what I mean, and is there really any difference in performance between vented and solid in either application?

Slotted solid with Mintex pads works for me

From recollection I think Isuzurover posted that vented rotors are much more prone to warping when suddenly cooled, i.e. mega downhill followed by a creek crossing, or even driving through a puddle on the road when the rotors are hot.

Might be worth a search Lockee before you go further.

OK that's valuable info.
now apologizing for a potential thread hijack, but is there any possibility of converting the rear solid disc setup (easily) into a vented one?

i.e. by using a front rotor setup for example....

just asking. I am not sure if there are any physical mounting differences between front & rear (offset versus diameter versus thicknesses etc) so if anyone knows, could they please enlighten me?

Not worth the effort since the fronts do most of the braking.

Probably vented front only came along when slush boxes were fitted. Funny that!

Don't think any RRC had vented rear.

I think that if anyone has to really ride the brakes that much in a RRC so that vented front are 'necessary' then something else is wrong, even with an auto trans.

I know people who do not realise you can leave these things in second (high or low range) or even first and get engine braking while doing massive descents.........towing a van haha. They just leave it in drive and ride the brakes, putting up with the smell, vented or non vented.

Mintex pads actually work better as they get hot in a major single stop situation.
