Brake Caliper Slide Pin Question

[EddieC]

Regarding rear brakes, when the caliper is removed, should there be any noticeable wobble of the individual (loose) pins in the bracket holes?
The pins were greasy and appear to be chromed and are without bear spots in the coating so if the slight wiggle is abnormal I'd wonder if it's the fault of the bracket holes rather than the pins. I think the pins are original but may have been changed once with the caliper(s). The truck has 140,000 miles in 18 years.

Cleaning off the old grease and applying new seems to firm up the fit.

Yes, those are guide pins. As the brake pad wears out those will go in and out to the bracket. Keep them lubed and they will be fine.

Thank but not the question.
Should the pins have noticible wiggle room in the bracket holes?

Okay, All we here is what u tell us. Purchase a full caliper set up and be done with it. Not worth the time and effort to mic the guide pins.

What I wrote was "Regarding rear brakes, when the caliper is removed, should there be any noticeable wobble of the individual (loose) pins in the bracket holes?"
Is that unclear?

Replacing the caliper and pins may not address a loose fit if the mounting bracket bores are worn.
But what constitutes a bad fit?

Now let me say I'm not trying to argue ur point but, no pics, no specs.... a video of the wobble? But in the end...... it's not aftermarket or upgraded brakes. Cause it would have been said. The pins are not made by or for a air craft mechanic. So there is play.whats unclear is what u call wobble.

Pretty sure that's normal.
If you put grease in, there's no obvious wear, and they don't bind or clunk, I'm pretty sure it's normal/fine.

One of the reasons I went to the later fixed caliper brakes..
However, it seems like the fixed calipers start grooving the disc more easily than sliding calipers for some reason..?
