Brake discs!

Hi guys, I looking for new brake discs and I was wondering which of these would be better? First of all would would the 17.5mm difference in diameter mean they wouldn't fit? In the sense of being better I mean as in Performance and more economical in terms of maintenance etc? What would your preference and advice be?

I just want to know what would be the best and more cost efficient on my car as it is a 1.2 Punto, 1998.

Thanks,
Allen!

Re: Break discs!

Drilled & grooved are not needed with modern pads and are more likely to crack. They used to be used on race cars to allow gasses to escape from pads running at high race speeds. On road cars they are not needed.

The car also needs the correct discs for its calipers. You cant fit vented to unvented calipers and they must be the correct diameter.

There is no point souping up the brakes if the wheels and tyres are not up to the job. Also A light car only needs light brakes. Too much and all you will do is lock the wheels and then take even longer to stop.

Some folks have greenstuff pads on standard discs and say they are better. Mine are standard and work fine.

The only mod I would make is to get plated discs so the non friction areas don't corrode. Alternatively have them stove enamelled over the non friction areas.

Too right. People often mistake drilling for weight saving - if you want lighter discs then make them thinner.

If your looking for a performance gain, get the discs skimmed on a lathe and buy better pads. (Ferodo? DS?)

Re: Break discs!

I've got ferodo Pads on Standard Disc's

Can easily get the Brakes to push the cars bumper into the ground
It can seriously stop hard!
thing is tho - you can only stop as hard as the tyres will let you

so correctly inflated tyres, tyres with a decent depth and Decent quality Rubber will all help also when having to stop nice and quick

If you're lucky to have ABS - Then simply plant the pedal into the floor, the cars abs will take over and do its best to stop you as quick as it can

Oh no it won't!

ABS is to allow you to steer while braking (a bad idea, but its what people do).

You can stop quicker without ABS.

Re: Break discs!

A good driver can do better without ABS, but most haven't got a clue what's going on outside their warm little box so for them ABS is better.

Got to say the one time I really needed ABS (busy m-way not in a Punto) it did a fab job with smoked tyres but no actual skids. I'm sure without it I'd have hit the car in front.

Re: Brake discs!

ABS can be a Miricle and a pain

Since i've never had it - i'm not missing it

I have practiced Stopping as fast as i can from say like 70
It aint pretty how far you actually go!

But On those times you think you have grip - and your dont the ABS can cover you
