Author Topic: any way to test clutch life? (Read 2899 times)

How do you know if your clutch is on its way out. The reason I ask is that the clutch grabs at the last bit of travel in the pedal. I don't think I feel it slipping, but I am not entirely sure. Is there any way to know if it is time for a new one, or should I drive it until it starts slipping? Thanks in advance!

You'll feel the clutch slipping if it's worn. Revs will climb on hills and/or high load situations.

The brake pedal range can be adjusted but I don't think the clutch can.

You can try bleeding the clutch too. There's a bleed screw on the top of the slave cylinder on the front-driver's side of the transmission. Just make sure the brake fluid reservoir remains filled at or past the clutch feed line so you don't pull air in! Find a friend of family member to operate the pedal & you can turn the wrench, and that's all there is to it.

search youtube for bleeding clutch slave cylinder with an spray oil can, pretty cool and one person job. Forces air back to reservoir.

Thanks for the responses guys! I have a weekend project to try out. Is it common for our clutches to need air bled out of them? I can only assume that is is the original clutch and fluid, since I do not have the service records.

It isn't too common to have air in there, but it is cheap & easy to check.

More typically, the spring fingers on the pressure plate sag over time and the slave cylinder/throw-out bearing can't travel far enough to fully disengage the clutch. The only cure is a new pressure plate.
