Hi folks - I’ve got a 2000 F-150 and have been experiencing a vibration when braking. Today I pulled off the wheels and checked the run out. Right rotor was 0.004” – Left rotor was 0.003”. So it looks like I need to have them turned. I’m surprised with the amount of rust on the rotor, enough that I cannot tell what the minimum rotor thickness is. Otherwise the rotor looks OK, the bearing and seal areas are fine and the rotor runs freely on the spindle. The rotor measurement is 0.990”. The front brakes were done in 2003, just before I bought the truck used from the local Ford dealer.
When I pulled the calipers off the outboard brake pads came off easy, however the inboard pads were very difficult to remove on both sides. After I had both rotors off I can easily see that the inboard pads were barely contacting the inside surface of the rotor.
I’m assuming that there’s a problem with the calipers in that they are only squeezing the outboard pad to the rotor and the inboard pad is just along for the ride.
The pads still have lots of life left, but I’m guessing that I need to get new calipers and pads and possibly new rotors. Has anyone else experienced this?
Any suggestions would be greatly appreciated – thanks in advance.

 

I think the slide rails may not have been lubricated. I didnt know about them and my passenger side caliper locked up. Luckily I caught it in time and all that I had to replace was the pads and grease in the bearings.

 

Thanks for the response, Big.

Sunday was a cool day for me. I watched the F1 race in the morning (awesome). Then I watched Indy (I think it's been 20 years since I bothered to watch one) and I thought it was great. I think that Danica did an awesome job. Then at 5:30 I watched the Coke 600 Crash Fest.
In between I replaced the rotors and pads on the truck - $400.00 later, sigh, but better than paying shop rates.
The disappointing thing about the brakes was that if the mechanic who did the last brake job had only cleaned up and lubed the sliding surfaces I’m sure that I could have gone another year before having to replace them.
I got out the 600 grit paper and polished all the sliders and lubed everything before putting it all back together.

 

$400? What the heck did you buy? New front rotors and new ceramic pads front and back cost $167 after tax.

And no, there is nothing wrong with your calipers if its still squeezing them together. Those pads must've been really stuck! are the thin metal guides (anti rattle clips) still there? The brake pads should easily slide in and out place by hand even with the anti rattle clips, if not your caliper anchor plate may be bent out of shape, causing binding.

Were the (outboard) pads worn evenly top to bottom?

 

$400!! i bought front and rear rotors (cross drilled and slotted) with both front and rear (semi metallic) pads for that much.

 

Easy guys - I'm talking Canadian dollars, which make a big difference. As well, we don't have the same market + competition that you have so our prices are usually a bit higher. To cap it off, in my provence we have the pleasure of giving 15% to the nice folks in government.
Any reasonable rotor up here for a 2WD F150 is at at least $100.00 each. Then any reasonable quality pad set is around $95.00 - so there was most of it. Then I also needed seals, and to be safe, I replaced the bearings. I also flushed and filled the system with new brake fluid. So it's not hard to go through $400.00.
