Leaks appear to be between the caliper circular serrated surface and the brass washers. Tried lots of washers to no avail. Any type of sealer I can use in that area? Thanks, John Fastest 300

I would check the calipers with some fine sand paper to see if its close to flat.. I have never tried any sealer being that is basically a lube to tighten the fittings and I wouldnt trust it to hold pressure.. it can be up to 2000+ psi

Thanks, John [/quote} There are different thickness washers. Sometimes the caliper hose hits part of the caliper if the washer is to thin and cocks the hose. Doug

I bought stat-o-seal washers off of jegs, they have a synthetic oring mechanically locked into the middle of the crush washer. Cured my leaks right up! They were 4 a piece though!!

Using the old ones seemed better than the new ones. You do not want any sealants or washers with seals made into them.
