Brake Chamber Nut Rusted On

I'm a diesel mechanic, so we have a lot of knuckle busters. I'm down here in Houston, and a tractor-trailer came in with a brake chamber problem. This driver runs north and south, encountering snow, salt, and a lot of rust. One of the nuts that holds the chamber on wouldn't move, so I got out the Kroil penetrant with silicone and sprayed the nut down, letting it soak in. I put the impact on it, and it freed the nut right up. Kroil penetrant/silicone is truly a life saver.

I restore antique vehciles

Kroil Penetrant with silicone has become an essential "tool" in my toolbox. As a hobby, I collect and restore antique vehicles, and I've tried just about every rust buster on the market, and I have found Kroil to be far superior. Kroil is the only penetrant I use in my garage.

Best working penetrating oil I have used!

Like every home gamer mechanic over the years I have tried just about every kind of penetrating oil at one time or another with varied success. Unless Kroil is not available for some reason I no longer waste my money buying other brands, when you need a product to just work as advertised I always reach for Kroil.
