I've got Porterfield R4-S pads and Goodridge stainless steel lines with Motul fluid, but I'd like to upgrade to larger rotors and better calipers. Has anyone attempted this? I have a '00 ES with the 4 lug hubs. There doesn't seem to be any factory based upgrades as there are for the '01 5 lug hubs. They can swap the 626 V6 cars' 10.8" diameter rotors and calipers for their smaller 10.2" rotors. I know AWR used Wilwood rotors and calipers to upgrade their 4x100mm hub equipped World Challenge Touring car. I emailed them but have not gotten a response yet. I'm sure this would require custom adapters to mount the calipers, but what else? Also, they upgraded the rear brakes to discs from drums, which I'm really interested in doing. I don't have any idea where they got the rear disc brake spindles and 4 lug hubs though.

I'm not racing, but I want 'em anyway. On another note, are there any special procedures for changing the fluid on an ABS equipped car? How do you evacuate all the old fluid from the system?

Eric, I would check out www.kvrperformance.com From my days as Escort Gt owner I remeber guy who had wilwood big brake upgrade from them.
Maybe they'll build kit for you, but expect to pay big $
As for changing fluid with ABS-nothing is different, you just disconnect battery to cut off power to ABS sensors. BTW same applies when bleeding brakes with ABS.
When I changed fluid, first I used sparay nozzle from spray bottle(like Windex) and "sparyed" most of brake fluid out of reservoir.
I wouldn't empty it 100%. Ater that it just goes down to bleeding brakes and keeping adding fluid. Having all whells off on 4 jackstands would help.
BUT I have no idea what to do if you switch from regular fluid to AP or Motul, I believe they cannot be mixed?Somebody, help!

Wilwood doesnt make any Protege brake kits. Wish they did (I tried to convince them but guess I didnt do a good job!) They said that if enough racers wanted them & enough distributors would commit, they would make some kits. But I have a feeling that would be alot of commitment to get them to do it. I've got a couple of other places I want to try. I dont really want them for the performance. Ours do good enough. But I do want them for the looks!

AWR produced a kit based on Wilwood components. If you look at Wilwoods parts list, they have tons of different parts to fit almost any dimension. It's mostly a matter of measuring your stock setup very well and picking the right parts. The piece that would need to be fabricated would be the adapter to mount the Wilwood caliper to the stock hub. The rear discs are another story. You need disc brake spindles and 4x100mm hubs to replace the stock drum setup. Those would most likely need to be imported from overseas.

Oh, Motul fluid is not synthetic, so it can be mixed safely with stock fluid. But why would you want to? That would reduce the fluids boiling point and effectiveness. I want to completely evacuate the system before I add the new fluid, including the ABS soleniod. Synthetic fluid is actually not recommended because it doesn't absorb water at all. So when water does get in the system, it will vaporize easily when it gets hot, and leave air pockets in the brake lines.

check out www.fastbrakes.com i'm pretty sure if i talk to the guy who owns the company pretty well because i helped him with a part of a kit for the crx. if there's enough of a market for it i think he might help us produce a few "one off custom" kits... check out his site in the meantime and i'll see what i can do... latas...

I have a 1999 Pro. Im planning on upgrading my brake system.
I have heard about swaping the rotors with those of a 626 Is this
true? What about the calipers?

Any one out there has the KVR cross-drilled rotors that are sold by
corksport? are they 4 or 5 lugs.

Will they work on a non ABS car?

Eric F

Swapping rotors and calipers won't work for a '99 or '00 Protege because they use a 4 lug hub and the 626 uses a 5 lug hub. You would need to swap the hubs and wheels also. This probably will work on the newer Pros with 5 lug hubs, as I doubt Mazda used different 5 lug hubs on the Protege and 626. They could swap the 626 V6's 10.8" front rotors and calipers for the Proteges 10.2" front rotors. Not a huge upgrade, but if you could get the parts cheap enough it might be worth it.

Eric F

You didn't specify which model your car is. I think TheMAN is saying that if you have a DX or LX with smaller brakes than the '99-'00 ES, you could upgrade to the ES's 10.2" rotors and calipers easier than the 10.8" V6 626 brakes because they are still 4 lug hubs. As I said before, the 626 brakes would require 5 lug hubs, rotors and wheels, and 626 calipers.

I have a 1999 g3 lx j-specs

Do you know if the drilled rotors that are sold in corksport will fit my car? 4lugs? I´ve email them twice with no answer yet..

thaks!

I've e-mailed some salavge yards on optaining 99-01 Pro ES 1.8 calipers with the bigger 10.2 rototars to upgrade my 99 lx 1.6 with 9.2 rotors, but have not gotten a replay yet. I'll keep you posted.

biknman

I said I'll keep you posted will just got the call from the salvage yard. For $250 I got the 10.2 calipers/rotors off a 99 ES 1.8 so that I can upgrade my 99 LX 1.6 with 9.2 rotors. They should be hear next week, I'll let you guys know how it goes.

good

I want bigger ones too, I usually have to drive all day, and sometimes they feel too soft at the end of the day. It might be due to my brake fluid also.......

Is there any aftermarket cross-drilled big brake kits that would fit the P5. I know Brembo makes kits for the Miata and RX-7.
