I have been cleaning my brake calipers and wanted to flush them in case I got any dirt or water in where the brake line attaches or in the piston locations.

Chances are that you have already introduced some foreign material or cleaning compound into the caliper which might require a total disassembly to clean.

BTW, Kerosene is used in CNC linear bearing as a solvent for cleaning dirty bearing and because it doesn't harm the rubber seals.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I have been cleaning my brake calipers and wanted to flush them in case I got any dirt or water in where the brake line attaches or in the piston locations. I am sure I can use brake cleaner to clean out the piston holes. I was thinking of setting up a gravity flow process where I could place a funnel at the screw hole where the brake lines attach (see arrow in pic) and then let some fluid drain through. So, is there anything instead of brake fluid, i.e. mineral spirits or kerosene that I can use to flush out the inside of any debris or water before I put the bleeder screws back in and that won�t damage anything inside the calipers?

POST 2Original post

awe - you know you have a sickness right ? haha hey, throw a coat of rejex or other wax on them and they will stay clean WAY longer - not sure what to "rinse" them with

POST 3Original post

Only introduce brake fluid into them. If you introduce something else then you have to work to flush that stuff out. Whenever you are done, block up the ports and then wash the calipers thoroughly to get the brake fluid off the paint.

POST 4 / ORIGINAL POSTEROriginal post

Quotes source post: 6859946

Ok, but brake fluid doesn't really work to get any dirt or water that might be in there out. At least, that was my thought since it's so viscous compared to something like Kerosene. BTW, Kerosene is used in CNC linear bearing as a solvent for cleaning dirty bearing and because it doesn't harm the rubber seals. I might just try that if no other suggestions come up.

POST 5Original post

Seriously - If you are asking those questions you might be better off to acquire four new or reman calipers. Chances are that you have already introduced some foreign material or cleaning compound into the caliper which might require a total disassembly to clean. Sunset is your best source for reasonably priced spares.

POST 6Original post

it looks obvious you used corks to seal the insides while you where cleaning them. Are you sure you contaminated them? If you insist, fill with brake fluid, seal the holes with metal plugs, and ultrasonic them. If you are feeling exceptionally OCD, use brake fluid in the ultrasonic instead of water and leave the holes unplugged! And try the G2 epoxy painting system, it works great (just did it myself). And if you do, just put the unused amount in the can in a plastic bag in the freezer overnight if you want to do two coats (just did that too).

POST 7 / ORIGINAL POSTEROriginal post

Marlon, just like everyone else, I am just asking a question so I can make the best informed decision. Anyway, I think I can pull them back from the brink of destruction.

POST 8Original post

No problem - just that disassembling brake calipers is best left to a pro bench. Otherwise you probably could use some pressure apparatus that might be beyond your scope. Alternatively you can just reinstall them and pressure bleed.
