do anyone have the same problem as me? after the engine bay gets hot from the turbo manifolds, my cluth feels like there is no prussure cluth. but after is cools down the cluth acts normal., anyone knows were to get a nismo or better cluch slate or pump? with more psi. or a longer pin travel for the pump., i put a heat shield over it, but it did not do much for the problem. thanks ahead of time.

 

Vaccum leak, look for leaks or the slave cylinder could be bad, check that....

 

thanks, i was looking to change it for a better than stock one. do you know if someone sells them?

 

I'd retain the stock one, there are 400+hp maximas running on the stockers. Just call DaveB 1-800-257-6060 and he can sell you one

 

Try the very highest rated brake fluid you can find. It might be boiling from the heat. ie.. like very hot brakes make the brake pedal feel like mush

 

i am going to try the higher grade fluid first and see what happed. now dave will he be able to sell me something higher grade?

 

My bet is that the rubber clutch line is getting spongy with the increased temperature. Switch over to a steel braided line.

 

I didn't think of the fluid temp issue or the rubber line, two very good points and do come into play.....

 

you think i could used hydrolic fluid isted of brake fluid?

 

It's best to use DOT approved brake fluids that have been tested for performance at high temperatures. If your hydraulic fluid wasn't made for high temp use, you don't know how it is going to behave when you use it in your brakes.

Brakes are something you don't really want to cut corners with or deviate too far from what the manufacturer has provided.

 

i am using dot 4 race gradeted on my brakes now, is there something better outhere?
