Don't know if the car is susceptible to it as I've done this too. Had a similar feeling in the clutch too but they share the same fluid don't they?

 

Brake didn't smell, just the pedal was very very soft and clutch gave no resistance at all to being depressed.

 

They can use the same fluid - they do not share it. Separate reservoir for the brake and clutch, You can boil the clutch fluid but it's not that common - Buster managed it at combe, along with his PS fluid - bloody nutter

 

You can also overheat the clutch plate - cooling should bring it back but if pushed when really hot you start to damage the flywheel and you can glaze the clutch plate then you get slip until it's replaced.

 

Most of this can be avoided by

 

1. Driving style/technique

2. Allowing adequate cool down time between runs.

 

At least your doing it in the right place and hopefully having fun - no better place to learn your car than on track IMO

I completely agree about the fun bit.

Possibly, but driving style impacts this too. Now you kinda know what to look for (though we can't tell if you overheated the pads or the fluid based on your description) you should be able to feel it coming on sooner.

 

Pad fade = it stinks awful, might get smoke too if you do a good job, but pedal still feels solid

 

Boiled your fluid = long spongy pedal, feeling of no brakes (Take a second quick stab at the pedal and you'll feel it bite harder.)

 

In both cases, the only short term cure is cooling.

 

Longer term - buy disks and pads that stand up to the heat better, be gentler with your braking style, bleed your brake fluid.

Thank you for the advice.

 

Brake fluid absorbs water, get your brakes hot enough and this boils to create steam, which is obviously a gas, which compresses differently to a liquid and that's why you get a long pedal and no brakes.

Thank you for the advice. It sounds like my brake fluid boiled. Changing my brakes in a few weeks to Ksport 256mm big brake kit and new fluid.

Did they firm up some time after cooling down?

No, I had to push all the way down on the pedal to get a small amount of braking. I had done a number of cool down laps and started to push it hard again. I should of stopped and allowed it to cool down.

Had a major scare when my brakes virtually failed when doing a experience day on a old airfield today.

It wouldn't of surprised me if I had been on standard pads, discs and brake fluid. But I have DBA T3's, Ferodo pads, a six brake line kit and Motul 600. It must of been my first experience of brake fade.

The instructor, sitting next me to me was pushing my car too hard me thinks !

Hi and welcome. Good luck with your search for your Z.

Welcome back.

If something sounds too good to be true, it usually is !

Hi and welcome.

Sorry to hear wot as happened. I will keep a eye out for your Z.

Hello and welcome.

Hi and welcome.

Hi and welcome.

This is a difficult one, as I like them both 50/50.

Do about 450 miles a month.

Hi, thank you for all the info. Wasso if you pm me nearer the time, I would defo be interested in buying red calipars.

Thank you.

Hi,

I intend to have my Brembo brake calipars on my 350z spray painted red. Does anybody on this forum know who is willing to do this for me ?

I have a resonated cobra system myself. It does have a small amount of drone at about 2500rpm. But I have got used to it, especially when I take it above 4000rpm and it roars into life!

I have also had my EML stay on with my high flow cats. My car doesn't drive any differently and it was the O2 sensors that was caused the EML to stay on.

Need to visit horsham developments to get the sensors switched off again, me thinks.

Nice looking Z, I would of been interested myself, but I brought my Z in May.

Good luck with sale.

Hi and welcome. However my Z is the best car I have ever owned !

Really sorry to hear about your bad experience with Junction 17.

I will be avoiding them.

I would also recommend Cougar Store.

Hi and welcome.

Hello and welcome.
