No it don't seem like an other problems with this. I have all the stuff to do it but I have 5 months before the weather changes so I have nothing but time to kill to finish this mod.

from my understanding the 01-up hydraulics was mostly just a slave cylinder improvement and not a master cylinder improvement. I have done this mod on mine and it works flawlessly but I knicked a seal and it is leaking down so I'm doing another master cylinder and going to be extra careful with the seals this time. My clutch does disengage alot better than before!!

If I'm not mistaking the seals that Thunder Racing supply are for the McLeod adjustable master cylinder. I don't know if they'll work on the stock master or not.

Correct, the seal for a stock master is a cup seal that fits a drum brake wheel cylinder. I dont have the number on me. They are cheap.

So the one from TR will not work with stock master cylinder and there's a stock seal available, right. 95 LS1 Camaro, can you post the part number when you find it?

Comparison of newer to old unit:

Newer Plunger Unit:

Old:

Newer Stop:

Old:


It is obvious that GM has changed the stop unit, hopefully I can achieve more slave cylinder actuation by increasing the length of the clutch master clylinder rod.

Just curious, did anyone end up getting the part numbers on the seals? Also is there anything wrong with the Brakeware (Duralast) MC or should i go ahead and purchase the LUK unit. From my understanding the LUK is OE


Motormite / Master Cylinder Gasket - part # 42072

Just saw this... will it work??
