Mixing brake discs...
Discussion
Not bonkers, just unsure and maybe a tad of OCD. Thanks for the quick reply though.
The car's still on the original discs at 60k and I've never had a car long enough to change the discs before. I've had a very bad experience of mixing tyres front to rear, and wasn't sure if the same would be true of discs. The pads would all be the same though, which I guess is the main thing.
Thanks again

a surprising amount of people are happy with miss-matched tires, the general public are generally speaking rather unaware how it can effects the handling in serious situations.. You certainly have to be aware of aware of how the grip differs in the tires in these events
Even when it comes to which new tires.. There is a lengthy debate on here if the new ones should be at the front or the back.
I'm with the school of thought that for safety regardless of drive they should be on the rear
When I bought my car it had two 'Infiniti' tyres on the rear and decent ones on the front. It would snap to oversteer on the lightest throttle opening in the wet, so much so that pulling out of a car parking space would mean oversteer (and I'm not talking about flooring it in first with lock applied, just normal pulling off...).
They didn't last long, I replaced them with a well recommended brand of tyre but left the original tyres on the front. Oversteer gone, but the superior grip of the rears vs the fronts meant understeer was always on the cards not to mention just a general feeling of 'uneasiness' from the front end...
Since then, it's always a set of matching, good quality tyres replaced in fours. It's far easier to predict what the car is going to do when all four tyres behave the same.

I had a vented Ferodo on the left hand turntable, the crowd loved it. I thought I'd spice things up by spinning up the cross-drilled Brembo on the other deck. I dropped the cueing arm and to my horror the holes snapped the needle! I fiddled with the desk and flashed my strobe light but to no avail. They pelted the stage with bottles and cans. I made good my escape under cover of the smoke machine.

Standard PH advice that drilled discs are always a bad idea. Heard it so many times it's become like a scratched record I had a vented Ferodo on the left hand turntable, the crowd loved it.

Dude, take it easy, he was only asking a question. Are you on a low carb diet or something?

forget the tyre issue.
You'll find that rear discs on most, if not all cars will be smaller than the front discs. Now can you think why that may be????
In fact, have you even LOOKED at your car or know anything about it????
I'm well aware that the discs are larger on the front, due to the fact that the weight will shift to the front under braking and so need to provide more force to stop the car. The discs in question are listed as being suitable for my car, however as they are different brands front to rear I was concerned about altering the brake balance away from standard.You'll find that rear discs on most, if not all cars will be smaller than the front discs.

In the same vein as putting mismatched tyres front to rear, I was concerned if it would have a similar effect on the car in respect to the brakes or if any effect would be negligible. Not an unreasonable question in my opinion...
The next question would be be, why are people such knobs?
The mind boggles. It really does. OP; did you know that you are supposed to fit brake discs four at once? It's true. Your car might explode in a fireball otherwise. Also, ventilated discs shouldn't be stored in confined spaces or they lose their ventilation.
While I'm here, people who fit tyres four of the same brand at once are just victims of the tyre warehouse salesman's patter.
Edit, in response to OP:
Honestly, and sorry about this, but your question is a bit silly, e.g, my car has a brembo four piston front caliper setup. Mercedes' discs for it are actually rebranded brembo discs. Brembo don't make rear discs for my car so they have to be "mismatched".

head so you have a matching pair on the front, and a different matching pair on the back?
So do you always put fuel in from a specific petrol company? REALLY can't see the 'problem'
If you're happy with what you've done then why ask?
The way your original post read was that you were going to put the fronts on theback etc. Which whoul be pretty daft.
Then again, you have an MX 5 so you must be pretty daft

No one, and I mean no one at all, "Needs a 308 GT4", unless the statement is proceeded by "Like a hole in the head".

Not sure if your joking... But I'll bite. While I'm here, people who fit tyres four of the same brand at once are just victims of the tyre warehouse salesman's patter.
The rear discs need replacing. The front are 'ok', but as I'm (planning on) doing my first track day in the next month or so, I'd rather get them replaced now and not worry about them.
As for tyres, if you've had a good experience mixing them; fair enough. As you may have read, I haven't and it seems others tend to agree. If we were talking about a car that was going to be exclusively driven slowly to, from and around town for shopping trips, then I would perhaps agree that it's not essential. I don't use my car like that, and prefer the predictability that's offered by having matching tyres.
If I believed the "tyre warehouse salesman's patter" it would have been to go with two budget tyres.

The advantage of better brands of discs is that they are less likely to fatigue or wear in weird and wonderful ways due to the iron being better cast and not full of carbon/pigs trotters/fairy wings.
It's much like tyres. Good tyres are good, bad tyres aren't - michelins on the front and eastern block plastic specials on the back will be rubbish, but two good brands, fitted in matching axle pairs will be fine.

OK. Any discs approved for the caliper application will give the same brake balance.

That's the sort of answer I was looking for.Gassing Station | General Gassing | Top of Page | What's New | My Stuff
