Got some D90 calipers for free, just need to rebuild the pistons/seal. Are the drilled/slotted rotors worth the extra cash over the solids? I have solid rotors on my D1 now FWIW.
Rotors for Defender calipers

That reads as a statement but sounds like a question.p m said:
I was under the impression D1 front rotors were non capatible with D90 calipers. No?
Solid rotors from Will T - drilled/slotted are NOT worth it, spend the $$ on better pads as its money FAR better spent.
And no D1 rotors will not work, you need vented rotors from a defender.

So it would appear these are 110 calipers. D90 and 110 calipers are the same, except D90 have a spacer between the halves allowing the use of a vented rotor. Right? The gap for the rotor is 11/16".
Is it worth it to rebuild 110 calipers for use on my D1? I am thinking yes because it uses larger pads and larger pots.

Sure - you'll have more braking power and better feel. The vented rotor will help with brake fade and help the brakes last longer. The 110's are worth it and spacers can be bought if you wanted to.
Anything to help these D1's - the brakes suck.

Any idea where to get those spacers? GBR maybe? I figure I'll check them out and see what the cost is. Trying to keep this low budget though since the calipers were free. Otherwise I would have just called Will.
Yeah, I thought it was also that the D90 pads were larger(greater surface area) and the pots(piston cups) were larger/had more force. No?sven said:

Then I realized my calipers are actually 110 and cannot fit the vented rotors. So I'm in the process of weighing the cost to benefit of this little endeavor with the free calipers.
Slotted and drilled rotors have less surface area, and don't brake as well as blank vented rotors. The slots and drill holes are there to dissipate heat under long periods of braking. Unless you have problems with brake fade, or tow a 5k trailer on a regular basis in the mountains, they don't justify the increased costs.

I think either the 90 or the 110 could have come with either solid discs or vented discs.
Thank you, that makes sense. I have no issues braking now. If I'm in the mountains or on a long decent I just drop it down a gear or two.Durt D1ver said:
I think I'll keep this as simple as possible. Two piston/seal rebuild kits. When my current D1 pads wear out I'll throw on the D110 calipers along with the free set of cheap Mintex pads I got. After that wears out I'll consider adding the spacers and vented rotors.
Thanks guys, helps me to think outloud sometimes.
GBR does sell the spacers.
I've had the D90 cals with slotted/ drilled rotors for about 4 years now and it's the cats ass. Providing the rest of your braking system is up to par.
Anyone who says you won't get brake fade without towing a trailer or going down a hill has no clue. Try driving in the desert for a day with constant braking.

i have a set of new in the box brembo drilled and vented front rotors that i want to get rid of...pm me if interested

I live in NJ, there's no desert within 2,000 miles, so sorry for neglecting that point.

No, it's not.
The Defender calipers have much larger pistons and much larger pads.
Personally, I do not see any advantage whatsoever to the vented rotors.
As soon as they are off back-order, I'll have these 110 calipers available for sale.
New calipers, hardware and pads should be somewhere in the $285 range, shipped CONUS but will be dependent upon availability and exchange rate fluctuations.
In the meantime Brett, if you want a rebuild kit, I can have one for you sometime late next week. Those calipers require a different rebuild kit from the Disco/RRC.
