Hard pedal, noisy brakes Exige

[woteva]

Have an 06 Exige S, which I fitted AP 305 discs to the front and 295 rears about 1 year ago. Standard calipers though, not 4 pot.

Ran RS42's for about 5 track days, and obviously it was a noticeable improvement.

So recently decided to step up to RS14's, and ran them last night for the first time at Brands Indy circuit.

Oh, and I also bedded these in exactly as recommended on the various Pagid reseller sites.

After about 2 laps, pedal went very hard and I just wasn't slowing down, accompanied by loud vibration/graunch that got worse the hotter they got. Backing off for a few laps improved things again, but the minute I leaned on them again I'd massively lose confidence.

Perhaps Indy is worse than normal on brakes. I've really only done Brands GP, Anglesey and Bedford with the RS42's and I never had a problem with either fade or pedal feel. And I've never done Brands Indy with the RS42's to compare directly, but certainly it would seem I'm having a major heat issue with the current setup.

Any suggestions? Should the discs have been changed before I installed the RS14's? (they looked fine). Am running proper fluid, although can't remember what at this stage, and this is regularly changed.

Cheers

To clarify, I said noise for some reason, it's actually shuddering. The noise is not at all an issue.

ABS? Stronger brakes overwhelming the tyres?

Improving the brakes without improving the cooling? What fluid are you using?

Its pad transfer. A well known problem on the 14's.

Try CL6's. Great pad without the pad transfer problem.

The 14's don't suit everyones driving style.
