you can access the inner lights by taking off the license plate and back up lights, if you can't reach the outer ones,remove the inner lights by removing two 10 mm bolts (i think they are at about 11 &5 o'clock) then reach in through the hole. It can be difficult if your arms are very big, but it can be done......just did it yesterday.
Take it to someone how knows how too.

No. There are three different tops for the C4 Corvettes, 84 to early 86, late 86 to 88, and 89 to 96.
check fuses first and if good more than likely the brake light switch is bad and that is on top of the brake pedal up under the dash.
Could be your starter.
They are run on the vehicles 12 volt dc electrical system.

Then fix them. Start by checking the bulbs - those are dual filament bulbs, and it's possible that the filament for the brake lights was compromised. If those check out, see if you have power to the brake light circuit with the brake pedal depressed by using a test light. If you don't have power, what I'd do next is find the relay and test that. Remove the relay, check for power at the 30 post - it should be hot constantly. Then check for power at the 86 post with the brake pedal depressed. If you have power at the 86 pole with the brake pedal depressed and at the 30 pole, then the problem is either the relay itself, or the wiring along the 87 circuit. If you don't have power at the 30 pole, check to see if there's a fuse specifically for the brake lights. If you don't have power at the 86 pole with the brake pedal depressed, the problem is somewhere between the brake pedal and the relay. I'd start with the brake light switch itself if that were the case. Should be located at the top of the brake pedal.
If the 85 is a similar bodystyle to the 86, yes.
Lift the vehicle on a car jack, remove the tire and set aside, remove the brake shoe/caliper and remove the old brake pad. Next, dispose of the old brake pad, put in the new brake pads, put the brake shoe/caliper back on, put the tire back in its place and lower the car.
