Why does your car engine race when you step on the brake?
Actually, there might be some kind of vacuum leak or bad vacuum connection somewhere. When you step on the brake, the power brake booster under the hood draws vacuum from the engine ... so it could be related to that. Check all your vacuum hoses and connectors for leaks, cracks or loose fittings. A quick and dirty fix for hoses with small cracks is to wrap some electrical tape around the cracked area. Such fixes are NOT RECOMMENDED BY EXPERTS, of course, but if they work for a day or two, they're likely to work for years.
