    Default How do people clean calipers?

    Dear Fellow Froggers,

    How do people remove the salts and other crud that accumulates in the seal grove?

    I've bent a jewlers screwdriver at right angles and I use this to pick at it. But surely there's a better way!

    Are there and solvents that are particularly good for this purpose which don't attack the aluminium?

    All the best

    I have never cleaned a calliper. (I've gave my vernier callipers a wipe with a rag once, does that count??)
    Am I missing out on something, or doing something wrong?????

    Hi Exfrogger, again. This is where a dremel and a wire brush come into their own. You can buy these days various brushes, not only wire (which itself can be steel, brass, nylon, etc). You can also have scotchbrite type little wheels of various grain (?), flappy sandpaper wheel and so on. Basically endless choice. These do a brilliant job of cleaning that pesky groove.

    But fear not. If you don't have a dremel no need to buy one. Bunnings or such places sell little wire wheels (again all sorts of materials) that are small enough to fit inside the calliper and clean the groove. A flexi drive is good but you can just stick it in the drill chuck and do it that way. Perhaps best if you can clamp the drill to the bench and hold the calliper in your hand, you have better control that way.

    Default Are you tearing them down and rebuilding?

    ATF 50/50 acetone mix soak them. Use 'cross buffs' out of something like this ( go easy as the 'buffing' pads can be agressive )

    Just be careful with Acetone on aluminum. Acetone tends to eat it if left on for a long while, well I got distracted once and a F!at 1300 SOHC head got very sad.


    -or-

    Are you just trying to clean the groves/bores without dissmounting them?


    Know a Dentist? Manual scaler is what I got off Fang, the prothetists also use these little bristle style 'Alpine' ? Brushes', like a wire wheel but made of stiff nylon bristles.

    Similar to the nylon rotary ones you find near the flap wheels at Bunings but smaller to get in the groves. They use them for polishing dentures or something.

    Be warned the scalers are sharp and their tips are as hard as.

    Thanks for the tips, guys. I find myself goings R8/10 calipers on a regular basis. I've found that media blasting is fine for the exterior buy can be a little vicious on the inside. The bores are small so the demrel tool could be the go.

    I typically take the caliper off the car figuring that if it has to be serviced its time for the brake hoses to be changed.

    I guess I was wondering if there's any product you guys know of any product that attacks the salts that build up in the grooves. I'll give the acetone and ATF a try.

    All the best
