First Brake Service- Need Clarification

[Zenkuto]

Just ordered Powerstop Z16 pads to replace the stock dust monsters. My question is will I need to or is it necessary to resurface the rotors since it's going to be a change of pad material? Or will a proper bed-in suffice?

Also, for the pad wear sensors, is it the same part numbers for front and rear? I came up with 47770-WAA01 and 47770-WAA02. So I'm not too sure if I could just buy two of the same ones or not.

If you bed the new pads in aggressively, you should be good to go. You need to get them much hotter than most people think to do it right.

You really really really have to bed them in hAAAArd. Like type-964 said, agressively

Otherwise you’ll feel the car shudder when stopping. Resurfacing can be as easy as using sandpaper on the rotors prior to putting on the new pads. This is a great way to go with ceramic/ daily driving pads. The rotors should last a long time. However, if you notice/feel a lip on the outer edge of the rotor were the pad used to be, then it’s time to change the rotors.

Hope that helps!

This is Powerstop’s recommended bed in procedure:


1. Perform 5 moderate to aggressive stops from 40 mph down to 10 mph in rapid succession.
2. Perform 5 moderate stops from 35 mph to 5 mph in rapidsuccession.
3. Drive for 5 minutes at a moderate speed.

I have a feeling this is not as aggressive as you guys are saying haha. Any tips on how “aggressive” to bed them, specifically?

I think I mentioned before, I interpreted the rapid succession part incorrectly and got shudder - once. Good buddy with his track Z4 described the process better. Used the word violently, for bedding them in. He got in my car and did the process for me. Much better choice of words ? Someone else on here (on another thread) mentioned if you don’t smell or see smoke - you probably haven’t bedded them in properly *(side note: don’t bring a passenger w/out a barf bag)*
