Hi there sounds like idle air control valve failure. Or also known as fast idle valve. I would suggest locate and clean. If that doesn't help then replace it and you should be good to go

if you look on the inside of the wheel you will see what looks like greese fittings you need to have somebody pump and hold the brakies and then you need to slowly crack it open by unscrewing it untill you get air then wait till it stops t5hen tighten it and pump the brakes again and do this again dont let the brake fluid run out of the resivore ok pretty soon you will feel the brake pedle start to get hard then do this a couple of more times and then you will be done ok best regardss mike

If you're going to keep that S10, and apparently you are as you are replacing the brakes, go to an auto parts store and buy a Haynes or Chilton service manual. It will give you step by step instructions, and will guide you on which tools to use to do any particular job. An investment of $15 - $20 for the manual will more than pay for itself in time saved and minimum frustration.

If your not sure leave it to someone who does, don't mess with brakes it could cost a life

Make sure battery has a full charge and battery connections all good, check fusible links, one of your positive battery connections should run to fusible links, where applicable. Ann\y fuses, not only check the fuses, check for voltage on the fuse circuit, use a testlite or something. Some fuses are hot all the time, some go hot with the key on.Ground is also important.

this could be due to a miss adjusted fast idle screw on the carburetor. if u have a fuel inject system check the Throttle position sensor.

Check all wires going to battery for corrosion. remove cables and clean connections, other problem could be at the starter. Get under the vehicle and check that all wires have a good connection and not broke/corroded.
