    Hey team,
    I had some minor pulsing at slow stops and I've been working through the scientific methods to rule things out. I got to the point where I greased the carrier pins and I may have found my culprit.

    My front right caliber's brake carrier is seized, specifically, it's the top pin. I've been using a tire iron and WD-40 (which I hate to use on anything brake related, but I had no other choice) and the SOB will not budge. I've even marked up the caliper a little bit (cosmetic, nothing bad...staying away from the pistons).

    To be clear, the pistons are operative and clean, it's merely the carrier.

    What I've done: Tire iron to pry it (NEGRES), WD 40 In the rubber cover (NEGRES), Beat it with a rubber mallet (NEGRS).

    What am I missing? What else should I do?

    Appreciate it, team.

    I sure you referring to pin # 9 Had them seize a few times pull the safety clip use a small punch hammer pin out. I have tried different lubes/anti seize with little success running gravel roads it gets seized

    It’s actually part 4.... this comes in to parts, the caliper and the carrier, you need to grease the carrier pins every year or so.... I guess I haven’t.

    A good habit is to lube or apply anti seize to the slider pins at every tire change. This is a very common problem.

    I was doing it every brake pad change.... but I’ve gotten good at engine braking, so it’s been about 1.5 years and 10-11k miles.

    I used white lithium grease, any concern with that impacting the rubber? I have anti-seize too... didn’t know if one was better.

    The grease can melt out of there if the brakes get hot plus it is not waterproof.... Clean it off completely and use the anti seize or Caliper Lube which is made specifically for this.
