How do you replace the rear brake pads on a 1994 corvette? is there a special tool you need to remove the e-brake cable?

If the emergency brake is built into the caliper this is something that will require special tools and knowledge to do it correctly. You wont save that much. Some shops will do a "pad slap" for cheap.

If it isn't and I am sorry as I don't remember, then no, you will not need any special tools besides some metric wrenches/sockets, a "c" clamp for compressing the calipers. once again, you would be better off finding a shop that will do a "pad slap" as the time you spend isn't worth the labor you'll save...

but you want a step by step, you tube has multiple videos pertaining to this subject and you can imagine how much typing would need to be done to explain what a 10 minute video will tell you

Remove the caliper mounting bolts and remove the caliper. Replace brake pads as necessary. Special tool is required to retract caliper piston to fit over new pads. (see picture below)
Retract piston in caliper using special tool to rotate clockwise and make sure the notch in the piston is aligned properly so the tab on the inner pad will fit in properly.
Reinstall caliper assembly and caliper mounting bolts.

For front brake pads replacement you only need usually wrench set, inclusive 7 mm allen key also. But for rear brake pads replacement you need obligatory a special caliper piston pressing tool, in order to press back rear caliper piston with parking brake automatic adjustment!!!
Instructions for front brake pads replacement.
For change front brake pads you must raise vehicle, remove wheels, extract the retaining spring of the caliper, and remove the caliper as follow:
1. Do not disconnect the brake hose from the caliper, and do not allow the caliper to hang by the brake hose!
2. Remove top and bottom caps (on back side of the caliper) for access to guide pins, then unbolt and remove them from the brake carrier. Remove the caliper.
3. Now you must thoroughly clean the brake calipers (free of grease).
4. Remove outer brake pad from brake carrier.
5. Pull inner brake pad out of brake caliper piston.
6. Check up the brake fluid level on the reservor, and emptying if neccessary!
7. Push piston back into brake caliper housing.
8. Install inner brake pad (with expanding spring) in brake caliper piston. (Arrow marked on pad - if exist, must point in direction of brake disc rotation when vehicle is moving forward).
9. Install outer brake pad into brake carrier.
10. Bolt brake caliper housing to brake carrier using two guide pins. Tightening torque is 25 Nm.
11. Install both caps.
12. Insert retaining spring into brake caliper housing.
Important note: Depress the brake pedal firmly several times while the car is stationary so that the brake pads adjust to their normal operating positions!!!
Check brake fluid level and top up as neccessary!

A special tool is required to compress the caliper piston on the rear brakes-don't use a C-clamp on the piston.
Raise the vehicle and remove the tire. The rear calipers have only one guide pin. Remove this pin and raise the caliper. Remove the old brake pads. Using the special tool compress the caliper piston-the piston will have one or two slots on it. These slots must in the correct position to remount the caliper. Install the new brake pads and slide the caliper back over the rotor and replace the guide pin. If the caliper doesn't slide over the rotor you'll need to reset the slots on the piston. Replace the tires and you're ready to go.

For caliper brakes, mainly a large C-clamp or brake cylinder piston tool, to collapes the piston back into the caliper, to install the new pads. If you have rear drum brakes, they make a couple different brake spring tools for removing the springs on the brake shoes.

jack up rear of car,put on axlestands/bricks,remove roadwheels,you will then be able to see what needs to be done to replace pads.no special tools required,but remember to smear back of pads with copperslip brake grease,stops em squeeking.(prise pistons apart with tyre iron)and remember to unscrew brake fluid cylinder cap to release any overspill,

Once the caliper is taken off the rotor a screwdriver can pop the pads off. New pads will have metal spring clips to attatch back on the same way.

One, take your brake fluid reservoir cap off.
Two, use a thin piece of wood to help you compress the piston on the caliper....do it slow. This way, you don't create a lot of pressure to the reservoir and it won't overflow.
Three, these are the steps to removing and replacing the pads for the rear. It does mention a special tool....but you can use a c-clamp for the same purpose:

Rear To Remove:

1. Check the brake fluid level in the brake master cylinder reservoir.
2. If required, remove the fluid until the brake master cylinder reservoir is half full. CAUTION
   Care must be taken when servicing rear brake components without disconnecting the parking brake cable from the brake caliper lever.
   
3. Remove the disc brake caliper. Support the caliper with mechanic's wire. CAUTION
   When the brake pads are separated from the brake caliper, new brake pads must be installed. The brake pads are one-time use only.
   
4. Remove and discard the brake pads and spring clips from the brake caliper anchor plate. NOTE: Do not remove the anchor plate guide pins. The guide pins are press fit to the brake caliper anchor plate. If the guide pins are damaged a new anchor plate must be installed.
   
5. Inspect the brake caliper anchor plate assembly.
6. Check the guide pins and boots for binding or damage.
7. Install a new brake caliper anchor plate if it is worn or damaged.

To Install:
NOTE: The left caliper piston turns clockwise and the right caliper piston turns counterclockwise.

1. Using the special tool, turn and compress the brake caliper piston into the cylinder.
2. Clean the residual adhesive from the brake caliper fingers and pistons using the specified brake parts cleaner. CAUTION
   Do not allow grease, oil, brake fluid or other contaminants to contact the brake pad or caliper mating surface. Do not install contaminated pads.
   NOTE: Install all the new hardware supplied with brake pad kit.
   
3. Install the new spring clips and brake pads.
4. Position the brake caliper and install the 2 bolts. Tighten caliper bolts to 23 ft-lbs (31 Nm).
5. If necessary, fill the brake master cylinder reservoir with clean brake fluid.
6. With the engine running, apply pressure on the brake pedal to seat the brake pads.
7. Test the brakes for normal operation.

im sorry bro i find that you needing special tools a load of bs. i may be wrong but i really really doubt it. brakes are easy. first locate the caliper and there should be 2 bolts holding that tight. loosen the top bolt and then take out the lower bolt from the caliper. the old pads should just fall out. remove the master cylinder cap. (the jug with brake fluid in it.) compress the piston replace the old pads and push the claiper back down on the rotor. tighten bolts back up pump the brakes till hard with the car off and then repeat for the other side.

rate as fixya if this is what you need. Thanks

1. Remove the rear disc brake caliper (2K327).
2. Remove the brake caliper bolts.
3. Lift the rear disc brake caliper off the rear disc brake caliper anchor plate (2B582).

1. CAUTION: Do not allow grease, oil, brake fluid or other contaminants to contact the brake pads.
   Remove the brake pads by pushing inward and rotating the pad up.

1. NOTE: Use a block of wood or used pad to protect the piston and boots.
   Retract the caliper piston (2196) into the rear disc brake caliper.
