Sticky Caliper Rant

[derekjmiller913]

I bought my 4Runner at the end of last year. Passenger front caliper stuck after I purchased it so the dealer helped with that one. Driver front was stuck so i fixed that a month ago. Last night the driver rear was hot, smelled terrible, and the wheel was waaaaaarm. So, now I'm ticked I guess...

The truck JUST broke 100k, and yes, it came from a salty beach region in the NE portion of the US, but dear lord... this is just silly. I've spent a ton already just for my truck to fail on me like clockwork. Has anyone else had these fail like falling dominoes? I guess this is the nature of buying used older trucks with mysterious origins...

END RANT.

It's the corrosion from the salt man. I've never had an issue with Toyota calipers on the 6+ toyotas I have owned.

When I changed my brake pads, I experimented with silicone grease all around the edge of the piston where it seems likely that corrosion would cause it to get stuck. Why silicone? Because the instructions call for "lithium soap base glycol grease" for some areas which is expensive and hard to find. Presumably that's safe for the rubber seals in the brakes, but silicone should be safe for rubber, too. I also used Permatex ceramic brake grease in areas that aren't near any rubber.

So far so good, but I didn't have any problems with stuck calipers before, and I have maybe only 5-10k miles on the brakes since I worked on them.

It's not a Toyota thing, it's a from New England thing.

The road treatment eats up the undercarriage of everything on the road.

It's the sole reason I no longer take my bikes out in the winter after the first snow , that crap needs a few rainstorms to wash it away.
