My LS430 has approx. 42K miles. The brakes work fine I inspected the brakes on all four wheels the other day and noticed that all the rotors looked OK but the pads thickness varied from 4mm to 5 mm. My questions are:
1. At what minimum thickness the pads should be replaced?
2. Where should I purchase the OEM pads?
3. What is the pads removal sequence? I mean first remove the hair pin/clip, then slided out the stainless steel rod, and then remove the brake pads?
4. Do I need to apply an anti-squeeling grease/lubricant on each shim?
Thanks
