What do I need to do with seep (slow leak) at the rear on one side. I see rebuild kits available for not too much, and I am a fair hobby mechanic who has tackled a water pump , rear link replacement, and brake pad replacement on my 300E.

Is the kit a reasonable thing or must I spring for a complete high dollar caliper. Are there things I should know to do the rebuild correctly. Do I hone the cylinder? or just steel wool it if no serious pitting exists?

Any suggestions appreciated.
