If you're experiencing clutch problems, such as:
* High clutch pedal: This could indicate air in the hydraulic system, a failing master or slave cylinder, or a leak.
* Low clutch pedal: This often means the master cylinder is failing.
* Clutch slipping: This usually means the clutch disc is worn out.
* Clutch dragging: This could indicate a sticking slave cylinder or problems with the hydraulic system.
Here's what you should do instead of trying to adjust it:
1. Check the fluid level in the master cylinder reservoir. If it's low, you likely have a leak somewhere in the system (master cylinder, slave cylinder, or lines). Top it off with DOT 3 brake fluid ONLY. (Never mix brake fluids!) Low fluid won't adjust the clutch; it will simply indicate a problem.
2. Bleed the clutch hydraulic system. Air in the lines can cause a spongy or high clutch pedal. This requires two people and a bleeding kit or wrench. Search online for "bleeding a 1991 Chevy Silverado clutch" for a video tutorial – it's crucial to get this right.
3. Inspect the master and slave cylinders. Look for leaks or damage. If they are damaged, they'll need replacement. This is a more advanced repair.
4. If the clutch is slipping or engaging too high/low in the pedal travel, the clutch disc itself is likely worn out and needs replacement. This is a significant repair requiring specialized tools and likely professional assistance.
In short: Don't try to "adjust" the clutch. Address any symptoms by checking the fluid level, bleeding the system, and inspecting the hydraulic components. If the clutch is slipping, it's likely worn out and needs replacement, which is a job best left to a mechanic.
