Brake Jobs (No rotors)

When was the last time you had a brake job done and didn't have to replace the rotors?

I can't see the pads themselves within the calipers so how can you tell if you're in need of a brake job? I just picked up a used Grand Cherokee with 106k on it. After an initial inspection by the dealer there was no mention of the pads needing replaced. Everything's fine for now, but...

I'd like to have the pads replaced before they score the rotors and have to replace them.

So, a Jeep Grand Cherokee has a brake wear sensor? How accurate is it and how does it indicate your pads are worn?

Tired of spending too much on brake pads AND rotors.

Thanks.

What on earth are you talking about with the brake wear sensor? I think you might be thinking of a squeeler, the little piece of metal that attaches to the pads and will contact the rotors and make a hell of a noise when they are getting low.

Best and only good way to check in my opinion would be to just take wheels off and check by hand. You can look down through the top of the caliper and see the pads and how much material is left that way.

Honestly basic rotors are cheap really no reason to not replace them if doing pads.
I think my duralast ones were like 16 each with lifetime warranty.

^ +1. Remove wheel & inspect for yourself is best. AS OEM configured there is no squeal device that I'm aware of.

I just realized how cheap rotors can be. I found them locally for 35.00 each. For some reason I was thinking they were going to be 70 or 80. I'll be replacing pads and rotors very soon.

Even if you don't have to replace the rotors due to them exceeding the minimum thickness spec, you should have them resurfaced whenever you change out the pads. How much life you get out a set of rotors and pads really depends on your driving habits, function of the rest of the brake system, pad compound and rotor quality.

While some vehicles use an actual brake pad wear sensor (a glorified magnet that gets placed in the pad and triggers a service light when the pads wear and the magnet gets closer to the rotor), WJ's do not have such a feature. Some aftermarket pads include a cruder version of this in the way of a small metal tab that is a attached to the side of the pad back plate and as the pad wears the tab will contact the rotor and make a squealing or squeaking sound when the brakes are applied.

Thanks, everyone.

I haven't done my own brake in over twenty years, so I take it in when I have to.

Disc and caliper are 100x easier than dealing with the drums, shoes, and springs that you are probably remember servicing.

Just make sure that the caliper pins are cleaned then greased when you do it. Otherwise they could cause the rotors to warp, overheat, or just plain mess stuff up if they don't move properly.

Regardless of whether or not you do them yourself. Make sure that those pins are lubed up in the front.

I need to do my brakes and rotors.
Isn't there a special kind that won't make awful noise when shifting gears?
I need to bleed my brakes too
