Hey guys i swapped my 92 camaro to a t5. I had a spare 4th gen 3.8l 5 speed pedal assembly lying around and installed it. My clutch does not fully disengage. I have bled the hell out of this clutch and it still doesn't fully disengage it. I could gave sworn I read on here these pedals would work. Any help?

 

They should work. Clutch not disengaging would be an issue with your slave cylinder, the clutch assembly itself, or one of the linkages.

 

Gotcha. I have to make these pedals work. I've bled the hell out of the clutch and it doesn't seem to be getting better

 

Are you getting a firm pedal at or near the top? If so, it's bled and it's a ratio issue.


Member pcopp just had the same issue w/4th gen pedals using a 3rd gen slave. He solved it by drilling a hole 1" further down the clutch pedal to get a longer piston stroke on the master.

4TH GEN PEDALS IN 3RD GEN

 

Not at all firm at the top. Not until about 1/3 to 1/2 way down. And I'm using a 3rd gen master and slave with 01 firebird 3.8l V6 pedals

 

Hmmm....that SOUNDS like the system isn't bled entirely yet.

Have you tried using the "back bleeding" technique? That method has proven to be "bomber" for me and my experiences w/bleeding hydraulic clutches. It works, it's fast, don't need to get under the car, and it wastes 0 brake fluid. Even starting from empty. Easy Button.

 

I have not. Can you explain the procedure?

 

Yep. Basically, you tap the clutch pedal, depressing it slightly -an inch or so? ...a bunch of times. Occasionally, I'll give a full pump/stroke, to move the fluid around in greater volume. As you do this, the air rises to the top and it uncovers the replenishing port...the air evacuates in the reservoir of the master. I can do the system in my 'Vette from totally empty to fully bled, using this method, in about 5 minutes or less. Same w/my '90's Silverado hyd clutch system.

 

Alright I've done that. That helped but the clutch still won't fully disengage. I wonder if it's the pedal ratio.

 

I had a similar issue had to take out the hydraulics out bench bleed them while moving them around to get the last bubble and then put in as a unit.

 

Anyone know what the clutch master cylinder stroke is?

 

Based on what you're saying, and the thread that cpopp started that I linked above, it sounds like more master stroke might help.

Changing stuff around when 100% stock parts work and denying that the changed parts are the reason is close to the definition of insanity.

It is mentioned on here in threads the 93-02 pedals have a shorter stroke than 84-92. If everything is equal, the 4th gen pedals push less fluid.

Could you run a larger bore master to correct? Yes. Could you run a smaller bore slave? Yes.

But the simplicity of a vehicle having "pedals to clutch from a 91 Camaro V8" makes parts and repairs simpler. Rather than ordering a slave for a different car, or having to order aftermarket master from Jegs, or whatever hoops to jump through you're creating for yourself. I would swap pedals.

 

fixed it. Moved clutch master cylinder mounting point down 1 inch. Clutch works flawlessly

 

Just like cpopp did.

Easy Button.
