Default NB 1.8 brakes on 1.6 car?

Hey,

Does any body know if stock brakes from a 2000 miata base will work on a 1991 car? Can the 1991 calipers work on the 2000's brackets? I got calipers, brackets, rotors and pads i can buy from a 2000 and wondering if they will work on my 1991.

Thanks in advance!

No.

There are 1.6 brakes, 1.8 brakes, and Sport brakes.

Ok, can you take a look at these two links i have. In both it says that you just need the brackets, rotors and pads from a 1.8. The one suggests you need them from a 94-97 but i have seen elsewhere that 94-02 use the same brackets. According to these two links the 1.6 calipers should work with the 1.8 brackets? Correct me if that is wrong, thanks for your reply.

I don't really know anything about 1.6 stuff other than that it's trash. If you have the complete setup available to you, then use that. Seems way easier and zero chance of failure.

It does make sense but the 1.8's are rustier and higher mileage compared to my minty 1.6 units. Would get the 1.8 cars calipers just to have as spares and clean them up, they will be cheap anyways but prefer to use mine if i can.

Anybody that knows more about this that can respond?

If you want 1.8 calipers / pads, you need a complete 1.8 setup. Nothing from the 1.6 imho is interchangeable with the 1.8 series of brakes.
In 01-05, Mazda created "sport brakes" where the pads and rotors were bigger. There is some interchangeablility between the sport and non sport brackets and calipers, but you'd have to dig into that rabbithole yourself.

If you want the biggest stock brakes you can get, grab a complete sport front and rear. If you want the most pad choices, pick up a non sport 1.8 brake setup.

Tldr: you want 1.8 or 1.6 brakes: you can't do both, Pads, calipers and brackets are unique for each.

This is highly inaccurate. 1.6L calipers will fit onto 1.8L brackets just fine. Since time immemorial, the "common" brake upgrade for 1.6L cars was to order pads, rotors, and brackets for a 1.8L car and swap them without changing the caliper itself.

Sport calipers will fit 1.6L/1.8L brackets in the rear ONLY. The front Sport caliper is completely unique and will only fit on a front Sport bracket.

The only difference between 1.8 caliper ans 1.6 calipers in the front is which hole is the big one is flipped. You just flip the brackets from side to side and you can use either caliper.

Source: I have 1.8 brackets and brake pads on my 90 and I just used the same calipers. (I have the m-tuned BBK though and use corrodo rotors).

The rears are the same, brackets just swap right on.

Thank you for the reality check Andrew with the 1.6 calipers. I just chucked em and went all in on 1.8.
