Brake question...
 

I have a 91 Miata with stock brakes, picked up some 1.8 brackets off an 02.

I was under the impression that 94-05 1.8 brakes are the same minus the sport brakes. The 02 Miata I got the brackets from had sport suspension? Does that include sport brakes, the Mazda guy couldn't tell me anything more than that.

Will these brackets work on my 1.6 with the 1.6 calipers?

With the standard swap, just 1.8 rotors and pads?

Put this in Race Prep because I was also going to ask about ads but already got my answer.

Leave hydraulics alone, use 1.8 non-sport brackets, rotors and pads, either front or rear but not both you will have to switch which side it says it's from - I don't remember which but it is very easy.

I know how to do the swap over, but I know sport rotors are bigger, thus sport brake brackets must be bigger as well.

If these are indeed sport brake brackets, will 1.6 calipers bolt to them?

I don't think the brackets you have will work, you'll have to buy all the rest of the sport brake stuff which doing correctly includes master and booster.

Edit: $hit I don't know for sure, thought I did...

Would the booster and master cylinder be necessary?

I like the feel on my 01, I do not so much like the feel of my 92 anymore so IMO, recommended.

Checked, not getting under my cars but google, the sport parts will not work with standard 1.6 or 1.8 brakes though those will work with each other - this part I have done. If you have to do sport, do all of it, otherwise just buy 1.8 brackets, pads and rotors.

Damm that puts a damper on things, it will cost me $40 for the calipers. Rotors are $35 a piece for sport brakes...Then the cost of pads.

I think I might be better off finding some normal 1.8 brackets so I can use my 1.6 calipers and save money on rotors as well.

Thanks for the help...

The sport brakes are great, but as said, the rotors and pads are more expensive, and it's usually not the best feel without adding the booster and master as well.

They are quite the hot commodity though. Your rear hardware is worth a pretty penny to most, as sport rears with TSE's 11.75" BBK is the best setup for track guys right now.

You shouldn't be out any extra money once you sell the sports and buy the 1.8 stuff.

You say the rear hardware? Does that include calipers? Or just brackets?

Your rears are popular because they allow adding of sport rears with even more agressive Wilwoods for the front.

I believe the sport rear brakes require the sport rear calipers and brackets. However M-tune's adapters uses 1.8 rear brackets with either 1.6 or 1.8 calipers with sport rotors, so if you hear that 1.6 or 1.8 rears work with sport brackets that's probably why.

Hope that makes sense.

What I understood.

90-2000 calipers are the same, 1.8 brackets just put the caliper further from the hub allowing a larger roter and larger pad. From the swaps I have seen people use normal 1.8 brackets on 1.6 cars. Change only the rotors and pads.

The mtuned brackets are for 94-05 normal brakes(non sport) they seem to bolt between the stock 1.8 brackets and the stock 1.8 caliper. Allowing you to use sport rotors but retain the normal 1.8 calipers so you have more pad choice.

Mr rear rotors would would require the sport calipers to use. MEaning less pad choice but still great options I suppose.

The brackets you use determines what pads you use.
If you use the standard 1.8 brackets and rotors and a sport caliper, you can use any standard 1.8 brake pad. You may have to trim the pad hardware.
If you use the sport calipers to run a larger rotor on standard 1.8 brakes, you have to run sport pads.

You cant do that at all because the sport caliper does not bolt to the other brackets and vice versa.

I have rear Sport Calipers on my non sport brackets. I had to clearance the stock (carbotech) pads slightly to fit. The car is a 91. I know this is opposite to the OP's question, but hope the info will help.

Let me clarify. I thought I had mentioned that what I said was in regards to the rear brakes. The rear brackets for standard calipers, do in fact bolt up to rear sport calipers, because that is what I currently run. I have both the standard and sport brackets for the rear. The standard rear brake calipers can, in fact, be bolted to sport brackets to run the larger rear sport rotor, as well.

Okay well IDK because I havent tried that way just normal 1.8 swap; just searched a couple sites but am curious enough that I might just try this tomorrow.
