is this moving when mobile , over bumps? check engine mounts, gear box mounts and also check that clutch slave cylander is secure and not loose
Answer: Normally located down by clutch arm (that sticks out between the engine and transmission). How do you locate it? The clutch pedal depresses a clutch master cylinder on the firewall (driver side). Follow the hose line down to the where the clutch arm is located. NOTE: don't get the brake master cylinder and clutch master cylinder confused, its easy if you do not work on cars regularly.
Brake booster problem?
This almost sounds like two problems or something that is causing both problems. It sounds like you have a nuetral safety switch that prevents the car from starting in gear unless the clutch is depressed. The other problem sounds like a throw out bearing problem not allowing you to shift into gear. I would check first to make sure that the clutch is being engaged when you push the pedal down. Probably the easiest way is to put the car in gear, engine off and parking brake off. Depress the pedal and see if the truck will roll. If it won't roll the clutch is not properly engaging. You will then need to figure out why. Has it become disconnected at the pedal? Is the throw out arm broken or bent? Hope this helps.
Depends on the type of transmission you have. If it's an automatic, check the transmission fluid with the vehicle running to make sure it isn't low. If it's not and the transmission slips you've probably got an internal problem inside the transmission. If it's a manual transmission it could be the hydraulic fluid is low if you have a hydraulic clutch, or it could be the clutch itself. If you've got an older clutch that's not hydraulic, it could be out of adjustment, or the clutch itself is bad.
There should be a bleeder located on/near the slave. Fill the master with brake fluid which is what the hydraulic clutch uses. Raise vehicle place on stands. Have an assistant pump the clutch pedal and after 4 pumps, hold to floor. At this time you loosen the bleeder screw to release air/fluid mix. Tighen screw and now the assistant can pump up system again and repeat the procedure 4-5 times; that should do it. Always keep the fluid in master full as it will go down fast. Good luck.
Actually if the fluid is coming down the clutch pedal it is probably your clutch master cylinder going bad or the seal around it. No worries it is a cheap fix. If it is coming down the clutch pedal it has nothing to do with your brakes. Some people well most use brake fluid for the clutch.
True
You have a broken clutch.
Fault with clutch master cylinder.
On a 1998 Ford Mustang : With the engine OFF - put your gearshift in first gear - put your foot under the clutch pedal and gently lift the clutch pedal until the pedal stops - slowly push the clutch pedal down - you will hear a click if your clutch needed adjusting and adjusted itself
Bad hydraulic cylinders.
hydraulics work because fluids are considered a non-compressible material. therefore when you put your foot down on the clutch pedal it pushes the hydraulic fluid pressure through the line to disengage the clutch. if there is air in the line the air bubble will compress (gases ARE compressible) and you will feel a "spongy pedal" and you will have to "pump" the clutch pedal to move that air bubble down the hydraulic line before you get a "good" clutch
The clutch pedal.
Broken clutch fork, or other parts.
I have a 95 Honda Civic with that exact problem. In fact the clutch was just replaced with all new parts about two months ago. Is it unsafe to drive? Everything else seems to work just fine. Except there is absolutely no resistance from the pedal until you get down to about 3/4 of the way down you usually would.
You may need a new clutch.
clutch needs replacing good luck! not a fun job
