Cortina Brake Options?
daveb666 - 20/1/14 at 10:48 AM

Had my first trackday Elvington in my Locost yesterday.

The car performed brilliantly with no faults, however at the end of the day I noticed that my front discs were blue!

I didn't experience any brake fade at all though out the day, the car runs an OBP pedal box.

I was hitting 125-130mph on the back straight so was certainly making the brakes work.

The discs and pads on the car are just 'off the shelf' bits.


Should I replace the discs and pads with some uprated ones, or look at buying a calipers widening kit/2.8 capri discs?

Like I said, the brakes performed well but if the discs have gone blue they're obviously getting very hot which isn't ideal.

I welcome your thoughts

First thing to try would be some better pads.

Btw, how did you get on with Elvington's noise limits? I used to do quite a few days there when noise wasn't a problem... my car's not particularly noisy, but a lot of my pals would struggle with the 98db limit there now.

Just waiting on a supplier coming back with a price for some new discs and pads. big_wasa has told me the pads on there are the moment are just OE ones - and if the discs have got blue they'll now be glazed anyway so will need replacing.

re: Noise Limits; I was actually quite concerned about this as not only is there a 98db static test but there is also an 87db drive-by in place all day. My locost has a fairly large silencer with a 2.0 zetec on TBs.

I passed the static "no problem" and no other cars on the day tripped the drive-by either. It may help that my tailpipe does point downwards slightly?

There was an mr2 there that was notably louder than mine but had no problems. There were also a few 400/500bhp Impreza's thereas well which weren't quiet; again no problems.

They dont worry when they are testing the Large Jet engines they regularly run up to full speed!

Unless you experience brake fade you don't need to change anything but you should check you have a return spring operating directly on the pedal and check you have sufficient air space above the fluid in the reservoir.
Changing the pad material will not change anything as the amount of heat energy the discs have to disperse will remain the same.

Completely agree with Britishtrident.

The only issue you had was hot brakes - and you were on a track-day doing 125-130 mph so no great surprise!

I would say your brakes work fine and the only thing you might think about is fitting some new discs.

You shouldn't expect to do that kind of 'work' and not damage/replace anything
