Toddie Posted November 22, 2017 Report Share Posted November 22, 2017 I did a track day in my 02 Boxster S in October where i experienced brake fade with vibration through the steering when the brakes were really hot, when allowed to cool by a couple of steady laps the brakes returned to Ok. The vibration went away when cooler as well, which i put down to the pads "Gassing" as they couldn't cope with the heat. The car had all new discs and pads just before i bought it about 5K ago. However now i feel on the road they have lost their bite/feel, i seem to have to apply much more pedal pressure than before to stop quickly, have i damaged / cooked the pads? is this possible? I am doing the NC500 next May, and am going to get the fluid changed, brakes checked etc when serviced in Jan, what pads do people suggest? Not really looking at doing more track days. Am i correct that Textar are OE Porsche pads? Link to comment Share on other sites More sharing options...
james_ly Posted November 22, 2017 Report Share Posted November 22, 2017 Does the pedal have more travel? If so then most likely the fluid cooked... Link to comment Share on other sites More sharing options...
Toddie Posted November 22, 2017 Author Report Share Posted November 22, 2017 @james_ly i have'nt noticed that the pedal travel has increased, however next time out in the car i will asses that. Link to comment Share on other sites More sharing options...

edc Posted November 22, 2017 Report Share Posted November 22, 2017 ATE Superblue fluid or the new name equivalent is more than adequate for fast road and track day use and good value, available from ECP. Pad wise, when you start upgrading there is always some form of compromise. The biggest one with more aggressive pads is either more dusty, some can be noisy, but most if not all won't have the holes for wear sensors. I currently have some now old-ish Ferodo DS2500 but will possibly try the DS Uno next time round http://www.ferodoracing.com/products/car-racing/racing-brake-pads/ The sensors are just shorted together and tied out the way. Add some GT3 brake ducts for about a fiver too. Link to comment Share on other sites More sharing options...
spyderman8 Posted November 22, 2017 Report Share Posted November 22, 2017 Certainly address the fluid first - the stuff OPCs use isn't up to use on track days. Link to comment Share on other sites More sharing options...
Carlos Garcia Posted December 14, 2017 Report Share Posted December 14, 2017 i just got the Ferodo DS2500, how you managed to get around the brake sensors? Link to comment Share on other sites More sharing options...
Buzzlt Posted December 14, 2017 Report Share Posted December 14, 2017 If they haven’t got the holes to fit the sensors then you cannot fit them. They work on a loop which if broken deploys warnings! Either cable tie them up neatly out of the way or cut the wires and join them together in a crimp. Obviously it’s up to you to keep an eye on them then so you don’t end up metal on metal ! Assume this is the same on a 986 as 987. Also beware mixing brake fluids. I read somewhere that you should not mix the DOT 4 and DOT 5 I think as they are incompatible. If you have used 5 before you cannot go back to 4. It is recommended that you stick with whatever was originally put in there by Porsche. Link to comment Share on other sites More sharing options...

As I've posted above. You don't use them as such. Short them together. For brake fluid the mixing refers to glycol and silicone. DOT 4 and 5.1 re glycol based DOT 5 is silicone. You can mix 4 and 5.1 if you want. What's more important is the respective wet and dry boiling points. Some DOT 4 have better specs than DOT 5.1.

Carlos Garcia Posted December 14, 2017 Report Share Posted December 14, 2017 Is the short them together part that i dont know how. I understand the sensor has to be in and cramped and tucked away, but unsure how to short them. Just to be sure. I have the pads but i haven't installed them waiting to understand better what to do!

james_ly Posted December 14, 2017 Report Share Posted December 14, 2017 You cut the wire and see that there are 2 wires inside, you just twist them together then wrap in electrical tape. Google image: Link to comment Share on other sites More sharing options...
