[Shop-talk] Disc brake piston explosion

[eric at megageek.com]

Well, not exactly.  My buddy has a 2006 F350 pick up.  He called me 
because the rear brake was squirting fluid.  I when up to where he was. 
Turns out all four (two on each side) pistons in the rear brakes looked 
like they had been smashed with a sledge hammer.  I've never seen a brake 
piston fail like that before, never mind all four on the rear.

Weird thing was the pads on the passenger side were worn completely down 
and the rotor was shot.  The driver's side pads were rusty as well, but 
had almost all their 'meat' on them.

Any ideas what caused it?

Thanks
