Brake Caliber Problems

[robert830]

I have a 2000 7.3 ext cab long bed. My frt caliber keep sticking and wearing out pads. I have grease the pins and also replace both calibers with the same results after about 10,000 miles. Is the a after market caliber that might do a better job or a fix.

Thanks

Wwhen you clean the pins, use the white grease that is made for brakes.

I like to wire brush the entire caliper. A dab of that same grease can be used where the pad slides in the channel on each side.

Also, another common problem is that the brake lines corrode under the outer sheathing and you dont see it, but the inner hose is getting crushed off so that the caliper can not return properly...... and usually you will get a pull to one side or the other depending on what side is being crushed.

Your thinking right about cleaning the pins, but you may have to slow down and clean more, use a wire brush attatchment on a drill......get things moving free like intended from the factory..... before the rust set in.

Use the lube intended for the heat generated in the brake system.
Make sure your lines are not internally corroded.

I hope this helps a bit, I am sure more advise is on the way!

robert, are you surfacing the rotors when you replace the pads (or replacing the rotors) because this could cause premature wear, and also, do your rear pads seem to wear at all....it could be that your master cylender is bad and not proportioning fluid to the rear, therefore doing all the stopping with the front.

that said, my biggest suspition is just pad quality. what pads are you putting on it. i put a set of cheap pads on my explorer one time just to get me by when i was tight on money. 10k later, they were worn out. i put a set of factory ones on and they have 55k on them with a good 6mm left........Marc

Thanks.
I installed new pads when I replace caliper and resurfaced both rotors. Its just seems that they start to stick and not fully rellease the pads after about 10,000 miles mostly the left side.

Thanks

Good call on looking at the rears. On that note, are the inner front pads wearing more than the outer front pads. If so, that indicates a hose issue. If the outers are wearing more, and the inners are looking good, the sliders are not releasing all the pressure.

what kind of pads are you using robert???

a lot of the time that is true....but i have seen if it is only one slide sticking (usually the lower), the inside pad will wear faster but it will wear at the bottom significantly more than the top........

I had the same problem with sticking of pads an found it to be the pistons that are made of a type of phenolic material. I've tried to find calipers with steel or stainless steel pistons but with no luck. NAPA used to sell rebuilt calipers with stainless steel pistons but I haven't seen them in some time.
The last calipers I got were rebuilt from motorcraft and came loaded with the pads. But they had the phenolic pistons.
