Now after 16 days I need new pads again! The last time only the inside pads were completely worn to metal. When I had the right front wheel bearing changed in September my ABS was messed up and only after the bearing and both front seat bars were replaced did it happen. The brakes would shudder when pressed after. A mechanic pulled the ABS fuse and it drives like normal. Except after all that I have had to replace my rear rotors calipers and pads 3 times and needs to be done already after 16 days. No mechanic understands and I need to get it fixed.

Hi,

Can you tell me if both inner and outer pads are wearing evenly? Is it only the rear? Do the brakes feel normal when you apply them? Have you lifted the vehicle to see if you can turn the wheels?

Let me know. Also, when you have one pad worn and the other isn't, either a caliper is bad, or more commonly, the hardware that holds the pads on the caliper mount cause the pad to freeze. What actually happens is the caliper mount is steel and can rust. As a result, the rust pushes on the hardware causing the pad to freeze.

Next, a faulty rubber brake hose can also cause issues. Let me know exactly which brakes are affected, how they are wearing, and anything you can think of that can help me diagnose the issue. As far as pulling the ABS fuse, that shouldn't cause this issue.

Let me know. Also, let me know if you can tell if the brake are dragging.

Take care,
Joe

Just the rear brakes. The mechanic lifted it and the wheels turn okay. It does have drag. Also, just found out I have both rear wheel bearings needing to be replaced. Only the inside pads wore out on the back brakes the last time around after 23 days.

If only the inner pad is the issue, I suspect you have caliper slide pins hanging up. That is where I would start. Also, if they are wearing out that fast, I suspect there would be a smell or excessive heat from the wheels.

One other thing. I realize the vehicle was lifted and the wheels turned. However, I would have a helper actuate the brakes and then release. At that point, I would see if they release right away or is there a delay.

Let me know if I can help.

Hi,

Wearing rear brake pads in 16 days wow! the smoke should've been burning. Would have gotten the rear brake calipers and rotors red hot and could have boiled the brake fluid in the calipers. Brake fluid will be broke down from the heat and will need to have a brake system flush. The rear brake hoses can cause a check valve when the inside rubber lining starts peeling will need replaced.The ABS brake system needs serviced and repaired pulling a fuse is not repairing it. This system controls the respective brake fluid pressures acting on the disc brake cylinders of the right front wheel, left front wheel, and rear wheels when the brakes are applied in a panic stop so that the wheels do not lock.
This results in improved directional stability and steer-ability during panic braking. Let us know if this information was helpful or if you been more information because we understand your brake system
