rear braking

I have a 95 jeep wrangler, and this might be a dumb question, but I need to know if under all normal working conditions, upon applying the brake pedal, say incase of an emergency, are the rear wheels suppose to lock up.

There is a point where all wheels will lose traction and lock. For instance on flat dry pavement at 60 MPH if you hit the petal realy realy hard you should be able to lock the wheels, by gently backing off stop the locking, and with a little added pressure you can start them to lock again. You can control this, by listening to the tires. In a well balanced system, the car will stop in a straight line, and ALL FOUR WHEELS will be very close to locking but under your control.

In almost all cars the rear brakes lock first because the rear is lighter, and tends to lift up as you brake, making it even lighter. This is very common in pickup trucks, because they are so light in back.

If your rear brakes lock with moderate pedal pressure at 30 or 35 MPH you have a problem.
