Brake Caliper Seal Removal Insight

If you are planning on re-using the seals, tweasers should be gentle enough. Spraying the bore with brake cleaner to remove old brake fluid could make the seals easier to get a hold of.

It's a fool's decision to re-use the seals. Mine should be hear today from Partzilla.

The dental pick worked perfect for the removal.

thanks

Brake cleaner can destroy seals.

True, but I would hope any substance used to make brake caliper seals would stand up to at least a quick spray of "brake cleaner". However, I'm with runner on this one. Put new ones in while you have it apart. They're old.

I've reused caliper seals lots of times, even ones that were already leaking due to corroded calipers & pistons. In cases where they're available and not ludicrous $ they should be replaced. Brake cleaner can ruin them, they won't be ruined right away, they'll sneak up on you later on forcing you to start over. Same goes for getting any petroleum based fluid on them. They'll be ok for a while, sometimes weeks, then suddenly you find that they've turned to goo. I've had crusty cylinders & calipers on boat trailers that were leaking; honed the cylinders, scrubbed the pistons, cleaned the seals with hot water & some scrubbing and back to running.
