DIAGNOSE – FRONT END DIPS WHEN I STEP ON THE BRAKES
by Jim Miller

SYMPTOM SUMMARY
The vehicle dips forward when the brakes are applied.

USUAL CAUSE
This symptom is usually caused by misadjusted rear brakes or weak shocks or struts.

DIAGNOSIScheckengine
The shocks or struts can be tested by bouncing the front of the vehicle several times by placing your body weight on the front bumper. Once the vehicle starts the up and down motion, remove your weight from the front bumper. The up and down bouncing should come to a stop after only one or two additional bounces. If the the vehicle continues to bounce, the front shocks or struts may require replacement. A tire inspection can reveal worn shocks or struts as well. Bumps and dips accross the tread of the tire can indicate failed shocks or struts. If the shocks or struts are in good working order, the rear brake adjustment should be inspected. Inspect the parking brake to make sure it holds. If it does not hold, operate it several times. This will adjust the rear brakes on vehicles with self adjusters. If the parking brake still does not hold, a visual inspection of the brakes will be necessary to determine the cause.

PRECAUTIONS, TIPS, and NOTES
Brake drums and rotors become extremely hot after vehicle operation. Use caution when working around hot braking components.

if the front brake acts first than the rear ,if the front suspension is too soft or if rear brake force is too less cause the car to dip from front. Air on the rear system may cause this problem.the given answer by JIM is also very good suggestion, thanks for JIM
