#1 of 2 Strange Brake Issue by dwf15010
Jun 14, 2010 (12:27 pm)
I have a 2000 Chrysler Town and Country w/ 70K miles on it. Last week I drove through some water, probably about 18 inches deep. The van sat for 2 days and when I drove it again the back drum was frozen. I moved it back and fourth in the driveway a few times and it broke loose, and I chalked it up to rust from the water. Today driving home I lost all of the brake pedal and the brake warning light came on. I topped off the fluid but there is still no pedal and it won't "pump up" if you pump the pedal. I'm trying to figure out if the 2 things are related or just coincidence that it has all happened within a week.Any thoughts are greatly appreciated!!

Just a shot in the dark..... The brake calipers have a rubber boot that keeps the caliper piston dry. This rubber does deteriorate over time and cracks do form. Usually this isn't a big deal.
But if you were going to drive in 18 inch deep water, you may have allowed water to seep through the cracks and inside the calipers BEHIND the rubber gasket. This would keep water sealed against the metal piston.....causing it to flash rust.
This rust could cause the caliper piston to stick. Basically, you'd hit the brakes and they wouldn't release completely anymore. It'd always feel like the brakes are on.
