Hi, I noticed my instrument panel and gages light either goes off or dims after a few minutes of operation and they frequently flicker off and on, especially when I run over a bump (but not always). This is on a 1984 cheverolet corvette coupe. was wondering if anyone had any suggestions or solutions to a fix?

recently I noticed a slow leak in my master clyinder, so I watched it for a few days, i noticed a burning smell (fluid leaking out of master clyinder and/or hose onto exhaust). Now all of sudden I can't go into reverse, i can put that shifter into the reverse position but when i release the clutch i hear a loud noise, all the other gears go into gear properly (and work) with minimal noise, but the reverse gear makes a really loud noise and the car will not move at all.
help please!!
