Popping noise in front end

[formula700]

Anyone know what the popping noise may be when I hit the brakes. It doesn't happen all the time only when I am stopping short.

formula700,
You will probably want to see the "Explorer Tips" section on Caliper slide pins, http://www.4x4central.com/tips2.html#caliper.

Hope that helps,
