I am doing the 08 upgrade but have a question. I have the Hawk LTS pads and see that there are 2 shims that go behind all four pads up front. I dont see how the shoe would retract with the caliper when you release the brakes. I see no retaining clips on the pads like on the rear set up. Do the pads just sit in the slides? That's it? Or am I missing somthing. I have a 09 shop manual and I dont see any retaining clips.
