Had my car on track for the first time today for a quick 20min session at Trax.

I fitted the grooved disc/Kevlar pad combo all round from Godspeed with braided hoses and dot5 fluid about four months ago.

I followed the bedding procedure religiously and the combo has been fine on the road, but they lasted a grand total of three laps before fading to hell and leaving me some apparent deposits on the disc as I've still got slight vibration under braking since letting them cool.

I'm hoping the deposits on the discs will burn off through general driving but I'll certainly be looking for new pads before my next track outing particularly as it'll be a longer day.

I'm not sure (yet) whether to just keep using my kevlars on the road as they're quiet and dust free and then invest in some track pads to be fitted in time of a track day (is this wise?) or to just replace for road and track use.

In the event of the second scenario, what's a good proven all-round pad? I've heard Carbon Lorraine Kelly's are dusty as hell and eat into alloy wheel finishes etc but I've not excluded them completely yet?

Any suggestions? Specifically is it clever/wise to run two sets of pads or is there a science behind having a consistent relationship between disc and pads?

Cheers!

 

pads build up their own layer of material on the disc to "bite" with............

2x different materials can cause contamination/flack of retardation issues.........

personally simply buy a good pad that suits your driving the most or temper your on track style........

 

We do not recommend these pads for track use and this is exactly the reason why , they are not a pad suitable for those kind of temps , we only recommend the kevlar pads for everyday drives that have some stick now and again.

For road use and mild track use we would recommend something like Orangestuff , and for road use and hard track use we would recommend Carbon Lorraine RC5+ , but these pads can be squeely on the road , they are not bad for dust and don't damage paint on wheels like the RC6 pads are.

The ideal way is to use the kevlars if they are suitable for you on the road , and get a second set of track pads and swap them over when your going to do a track day.

The deposits will clean off as you drive around

If you need any advise please ring me

Thanks gents, much appreciated.

Ian the kevlar pads have been awesome on the road with not so much as a peep and minimal dust, so no complaints there.

I wouldn't say I was overly heavy on brakes on track, certainly not stomping on them as I was still building confidence/feel when the pads gave up on me.

I guessed as much re: mixing pads on the same disc so I'll aim for a set of pads which are suitable for the road too.

Is it the pad-disc contact on the RC5+ which squeels or is it the backing of the pad?

 

Even if you are not hard on the track , you will still be hitting temps much higher than you ever will on the road

You will get pad material on the discs as this is how they work , changing pads would not be a problem but it would only work properly after covering some miles to clean them off and put down a new layer of the different pads on the discs

The RC5 pads are a sintered pad , so its probably a mixture of both , but can be helped with ceratech paste applied to the pads
