Gen 2 front brake rotor upgrade
« on: August 29, 2017, 01:12:26 PM »
Many Montero Sports came with a larger front brake setup than what the standard Gen 2 brakes have. It utilizes the same calipers and pads but 314mm rotors instead of 276mm rotors - this upgrade will only increase braking force slightly since the pad-to-rotor contact area remains the same, but it should make a significant difference in heat dissipation.

The necessary parts (brake caliper brackets and backing plates) can be sourced from any Montero Sport with the 16" wheel package - note that 16" wheels are required to clear the larger brake setup, stock 15" wheels won't work. I discovered that the 2wd Montero Sports have aluminum caliper mounting brackets while the 4wd versions are identical but made of steel. I chose to use the steel version since Mitsubishi evidently thought the extra strength was necessary. I sourced new OEM rotors from my local Mitsubishi dealer for $80/each.

I had an issue with the original brake hose being a little too short to reach the caliper in it's relocated position when the steering was at full lock. I temporarily removed the brake hose bracket to give it some extra length and am going to have some braided stainless lines made with some extra length built in. Alternatively, I would assume that installing a Montero Sport lower brake hose would solve the problem.

Attached photo shows the stock brake components compared to the Sport brake components.

Is it official that the larger montero sport brakes won't fit the stock gen 2 15" wheels? I need to do my brakes and I don't want to upgrade with one buying tires/rims. Anyone have experience?

Could I get a clarification on the aluminum brackets. Is there a particular year for these in the 2WD chassis because I seem to be finding just iron brackets. I have not chosen to just buy a set to gamble if I get Iron or alloy.
I am giving thought to go with PBR alloy calipers instead but I have quite a few sets of pads for the Montero fronts.

I didn't look at the year of the 2wd Sport that I found the aluminum brackets on, but the bodystyle was the same as the 4wd Sport I found the iron brackets on, which is why I assumed it was a 2wd vs 4wd difference.

I have been trying to figure out some of these parts in ASA, best I can tell ASA shows the choice of brake rotors for 15 or 16" wheels but no selection of any caliper or bracket differences between the rotor sizes. Just show the 15" size parts.
 Kind of a PIA here in the northeast where we do not have pick & pull yards within driving range.
