No, the standard rotors with larger defender calipers will only fit under the 16" wheels. You'd need to go to 18" or bigger if you wanted to fit physically bigger rotors in there.

If you're cooking brakes then your driving style is probably to blame, not the rotor size.
After ridind mountainbikes with EBC green pads, I'd never use them in a vehicle, they fade far too easily. Sintered metallic would be my next stop.

yep..though so...ok will try change of pads...

but which ones?? there are so many claiming to be the best...

car is rangie classic..31 tyres...nissan 6 pot turbo diesel, intercooled tuned etc...+2 inch..has some extra steel on it

its that you driving well within your/my limits...then a sod off 1:3 or 4 or 5 wiggly downhill comes along..not using excessive braking(mostly engine) you get fade..its not the fluid..and the jap box suv sails past having no problems..!!!..i know my vehicle weighs alot..but!!

I have to agree with Zen. Standard Rangie brakes are good only for unladen vehicles used lightly. I have tried new rotors, slotted rotors all differnt types of pads, regularly change the fluid but the brakes still overheat. I regularly run out of brakes on long down hill runs, not even pushing the car. The road drive from Matlock to Woods Point or from Olinda to Ferntree Gully (for those in Melbourne Australia) leaves me with smoking brakes and no pedal every time.

Fit defender front calipers 46mm.

fit green stuff pads.

Toorak Tractor, Adrian I think had a set of porsche discs and clipers under his rover. was not cheap to do..


Michael.

I have heard of Jaguar calipers being fitted.
The only time I have had fade (and burning smell) is going into Kangaroo valley with my camper trailer on, when I didn't change down.
Maybe a different driving style of using the transmission for slowing is called for. I used to do this all the time back in the drum brake days Sonny.

Seriously, use the gears before you kill someone. Your kidding yourself if you think any 2 ton plus vehicle can absorb that much heat through it's brakes.

i do use engine braking..1st gear usually does the trick..but it WOULD be nice to have decent brakes..it must be possible...??

Depends what you mean by decent. My rangie is 2.3 ton and now stops as well as my nissan wagon which is almost exactly half that.

When I fitted the new brakes and pads I went for a drive to "bed them in". Driving up to 80km/h, braking down to 30 then repeat. They got hot enough that I could smell the paint cooking, got out and they were smoking. Still didn't have any fade issues.

Semi-metallic pads will let you run the brakes at higher temps without fading, but they probably chew through rotors faster.

Hi again Kiwibacon,

Initially I took your comment about 16" rims (above) to mean that the 46mm calipers need 16" rims to fit inside.

That's probably because that's what you have.

Will they fit inside 15" rims?

TIA, DL

If they will fit, they'll be very very close. Can anyone try it and tell us?

Hi KB,

Do you mind measuring the gap between the top of your calipers and your 16'' (?) rims, OR the height the top of the caliper is above the outer edge of the rotor. No hurry for this- flat out working myself.

I've got 15 x 8 Hurricanes, so the caliper is very much inside the rim and I want to make sure this great upgrade will fit.

Thanks, DL

Whoops,

Just saw your PM. 10mm or 12.7? Might be better for me having the measurement from the outside of the disc to the top of the caliper because of my alloy rims.

Thanks mate, DL

No problem, will get the measurement tonight.

1 finger worth of space in vogue alloy wheels.
That's about 15mm.

Inside diameter of a vogue alloy is approx 390mm.

Does anyone know where to get the spacers so that you can fit the vented rotors. I want to upgrade the wife's 97 Disco to vented front.

I have seen kits before that consist of the spacers o rings and bolts.

Thanks

discovery autos here in perth have them. They did tell me they aren't adr compliant tho.....
