Hey guys,

Historically my front brake pads have lasted me about 50-60k total.

My driver side brake started pulsating and the brake pad has worn down to the backing. This is with 31k on them.
The inner pad has more life on it, but the outer pad is completely gone.

Need some advice on what to do?
Do I just replace the pads, clean and regrease the sliding areas on the caliper (which to be honest I have neglected doing) and check it every 10k miles and see if it repeats? Rebuild the calipers on both sides?
