When the clutch pedal is disconnected from the hydraulics altogether. How should the return spring be making the pedal react?

When the clutch master cylinder is disconnected from the hydraulic line and the truck. How can you tell if it is functioning correctly?

Some newbie questions I could really use the answers for...

Thanks!!!

What is happening Paul?

It does depend on the year of your vehicle, the model,and if it is a 4 cylinder or 6 cylinder.

The 4 cylinders have an arrangement to where the return spring is attached from the pedal to the collapse bar. It gives a feeling of tension all the way through the stroke of the pedal, if the master cylinder is disconnected and moved away from the pedal. It is a "return" spring only.

The V6 trucks and 4 runners that I have seen have a cylindrical "helper" spring design. One side of the spring is hooked around the pedal and the other side is hooked against the pedal bracket. When the pedal is all the way out, it requires pressure to push it in. Once the pedal reaches about 50% throw, the spring helps push the pedal to the floor. If the master cylinder is not hooked to the pedal and the pedal is pushed to the floor, the pedal will stay there. This "helper design" is due to the larger master cylinders and clutches used behind the V6 engines that require a slight amount more force to disengage than the I4 clutches.

 

Hey,

Great information!!

I think my problems actually just that I don't know how to correctly bleed the hydraulic lines. I plan on learning how, and doing so ASAP.

If anybody has any helpful tips that would be great.

Thanks again,

Paul
