    brake caliper question

    Hello,

    This is could very well be a dumb question but....I have Cleveland wheels and brakes on my super cub. Is it "normal" for a caliper to be a little loose to the touch, such as when the brake pads are worn? one side is tight the other is loose, which I just noticed yesterday. The play seems to be on the 2 larger bolts.

    Thanks fir the input.

    I'm no mechanic. But I think the two 'larger bolts' will be the pins shown on the left. And yes there should be some movement on those pins. I think the calliper that doesn't move may need a closer look at. If my memory serves me, it's the only place graphite is recommended on our aircraft types. (But I'd have to go back to The Mechanics Toolbox to re-read that)

    Some good YouTube stuff on callipers.

    Robbie Grove says graphite on the pins. Without pressure you should feel just a bit of looseness. If you lube up those pins with grease or oil, you could start to get chatter. You don't want chatter. I had to go to new pins and torque plate on a chatterer.

    Another thing to check, make sure the brake line(s) are not side loading the caliper making it/them difficult to slide. They have to move freely. I spent three rounds of removing brakes and lubing pins until someone smarter than me pointed out that the brake lines looked pretty the way they were routed, but they were side loading the calipers and impeding the ability for them to slide on the pins properly.

    This was on McCauley brakes on a C170B. Same thing would apply to any brakes that need to float on those pins.

    I would cycle the brakes a few times. Check that your pads have a minimum .100" thickness. Cleveland says to lubricate the pins that the caliper slides on with silicone spray. Won't attract dirt and wear.

    That is a disk brake. So the caliper holding the pads has to "float" movement is good or the inside pad would always have pressure and wear out sooner.

    Looks to me like someone actually grabbed a grease gun and tried to grease the brakes....idiot
