      Your brake pads may need replacing, the disc or drum may be warped or cracked, the caliper may need replacing, especially if there is metal on metal friction.
      Floating caliper (single piston) designs are subject to failure due to sticking which can occur due to dirt or corrosion if the vehicle is not operated regularly. This can cause the pad attached to the caliper to rub on the disc when the brake is released. This can reduce fuel effiency and cause excessive wear on the affected pad. Additional heat generated by the constantly rubbing pad can lead to warping of the disc also.

      Remove the self-adjuster / star-wheel adjuster, separate the two halves where it is threaded and put a tiny amount of anti-seize compound on the threads and make sure that there is an "L" stamped into the end of the adjuster when you remove the end cap indicating left side.

      Mske sure that the hole where you adjust the brakes with a spoon has the rubber plug installed in it to prevent road salt from intruding right to the adjuster.

      The word fair is vague and subjective. Repair costs are tied to the amount of hours or parts of an hour times the shop hourly labor rate. A typical rate is $80 an hour plus parts needed. A 3 hour repair is $240 plus parts.

    2001 Yukon SLT,5.3L is limited slip axle or non limited slip axle?
    I'm about to get front and rear brake disc,but I was told to make sure if my car is with limited slip axle/differential or non limited axle/differential
    • Jay Giron

      A limited slip differential (the gears in the rear end, not the transmission) has clutches that distribute power evenly to both wheels, limiting the amout of wheel spin.

      An open differntial (non- limited slip) has fewer moving parts. It sends power the the wheel with the least resistance. As long as you don't spin your tires, (drag racing, snow, mud) an open differential is perfectly functional and less prone to noise and failure in the long run.

      These stupid answers really burn me up. As if I don't have the basics. Look nerds, I just need to know if I can expect better performance from slotted rotors or different composition brake pads.
      1/1/2012 Dave
      I have a fithwheel camper that I tow on vacations. I set the trailer brake actuator to stop my f250 and my trailer. It's the best way. I think u can add the electic brakes to the camper. I also have several work trucks with toolbeds on them that are very heavy. We r constantly doing brake jobs. Yes, The
      Larger slotted rotors with oversized calipers will help.

      Logjam -why the poor attitude? You asked for help - you got it. Just because you don't like the answers....
      The advise is sound - go the the place where the trailer hitch is installed. The improved braking performance may be relaized by either different brake pad formulation and slotted rotors - for cooling.
      But the best source of information would be the trailering experts.
      1/1/2012 Logjam
      look, the trailer hitch etc were factory installed as was the trailer brakeing unit. I never said anything about U-haul, it's just that I don't appreciate answers from a professional site, by unprofessional people. Thanks for the constructive answers, all are appreciated. Just don't tell me to go to the hospital where my baby was born to get an answer about teen-age masturbation ok!

      Call local U-Haul ( your moving and storage resource ) to have an accurate answer.

      Note : they provided and installed the trailer hitches.

    I bought this truck 3 years ago with 26000 miles on it. With-in a year the front disks were showing signs of cracking. I have replaced the front and rear pads twice in the 3 years. I know that I need to replace the brakes but I am concerned that OEM brakes are ...

      yes upgrade rotors; raybest, and drum brake stop tracker trailer. do you have a trailer brake on your trailer? if not i would get one........................
      12/27/2011 Clark Myers
      The boat ant trailer are 25 years old and there are no brakes. I looked into adding trailer brakes about 18 months ago but found that there are no flanges on the axle or frame which would allow mounting of calipers. I would have to buy a whole new axle in order to add brakes (about $1000 for the axle and another $1200 for the trailer brakes).

      It may be more cost effective to buy a new trailer with brakes.

      1. Disc rotors, brake pads, brake shoes ( some models may still use it, if the hardware such as springs are too rusty, replace them ) and Permatex disc brake quiet to avoid the squealing.Visit this site and see the Permatex. Local auto stores have those in stock.

      2. Visit this link and see the instructions to perform the repair.

      If you got to Autozone theyll help you get everything you need, if you do replace the rotors youll be doing your wheel bearings too as they use rotor hub assemblies, and among the stuff CVO mentioned youll need brake and caliper grease, and most likely the caliper pins and boots will need replaced if you have to replace the rotors

      If there are no brake fluid leaks, and there is no air in the system, then you'll probably need to replace the master cylinder.
