Excessive pad wear

[Cummins12V98]

When I get home in May I think I will replace the hoses. I did slip rubber hose over the needle nose vice grips to stop brake fluid flow when changing from old to new caliper. Could have caused damage to the hose since it was almost 20 years old.

Yes that is correct.

So if the other side has a bad line or stuck calipers it will put more fluid to the side that’s wearing faster.

Had calipers stick due to swollen rubber lines on old chevys.... fluid goes in under high pressure, then cannot return resulting in a dragging brake pad (or worse smoking pads)

 

[Cummins12V98]

OK, I will replace both rear lines and then check the caliper to see if it moves freely on the "GOOD" side.

For now it works.

We're talking rear here right? Although there's a single feed to diff (hose) do not each caliper have a hose as well? I'd replace all rubber hoses especially since you mentioned clamping one.

Rear correct. Yes I will replace all hoses in May and at that time see how the "GOOD" side caliper feels.

Without pressure gauges we are all guessing, but if you clamped a rubber hose, start there. Do you tow a lot? Easy on the brake pedal? The rears apply first usually and will wear out quicker with a load on if the driver is easy on the brake pedal.

Tow a 7,500# boat/trailer often but I don't hit the brakes hard as the controller is set properly and I did the 3rd gen front brake upgrade. The brakes work awesome!!!

I did clamp all the hoses as I changed out to all new PowerStop calipers. I used long nosed needle nose ViceGrips with rubber hoses slipped over the ends to make a soft compression.

The one pad went quick and other three look great.

That is a symptom of a stuck/sticking caliper slide.

 

[Cummins12V98]

It's possible but they looked good when replacing the bad pads. The calipers were PowerStop US Made and I used quality lube on all mating surfaces and slide bolts. But yes that sure could have caused it. Frustrating since I used all new QUALITY parts.

When I get home I will do the hoses mostly because they are 20 years old and then clean and lube that caliper along with the outer side. I will be checking how the pistons move.

That does nothing to help a stuck or sticking caliper piston.

I was responding to his comment on “stuck/sticking caliper slide”.

I do understand a stuck sticking piston has nothing to do with lube.

You can use the sponge type ear plugs in the banjo ends of the brake line to slow leakage and reduce potential for air infiltration when changing calipers. I've been able to use a Golf Tee when I had rear drums.

Joe Mc, the ear plugs are a GREAT idea!!!

I will add that to my very useful items list.

Thanks, kinda just came to me as I was wondering about another way to stop fluid flow other than the clamp-off the hose method. Might not fully stop the draining but should slow it down substantially and best part reduce, if not eliminate, air infiltration.
