clutch pedal issue(pedal inconsistency)

[paintball4fun21]

My clutch pedal is acting up..............basically its mostly fine until the engine warms up and gets hot ( its worse a lot when the temp is really hot outside) the pedal becomes lower to the floor and is really really spongy......it becomes harder to shift into gears..........If it park it for a few hours and let it sit and cool off its fine.....until i drive it for awhile and it warms up again.......it wasent a big deal this winter but now its getting 60+ degrees out and its really bothering me........im thinking its maybe the master/slave? i dunno
any help would be great

They don't swell with heat, they don't break due to dry rotting of the rubber, and they might just out last your DSM or Evo VIII! They come in the perfect length for your First, Second Generation DSM or now even the Evo VIII. They are a direct bolt on that will instantly make your left foot feel more comfortable launching that Mitsubishi hard! They are made to be a perfect fit and can be bolted on usually in under an hour!

If you have MUSH PEDAL this is the part your looking for! Once you replace your slave cylinder and reassemble with this line your clutch will feel better than ever!

Full replacement of clutch lines is unecessary. Just do a bleed. I suspect water or air in your lines somewhere.

You can, however, get the reservoir eliminating SS line in the first link while you're doing the bleed. RRE also offers it for $25: http://www.roadraceengineering.com/ecldrivetrain.htm
