Re: Brake Caliper Failure Just as I thought, the hissing sound was the fluid coming out of your ruptured brake line/hose. In over two decades of working on cars on and off, I've never seen a caliper leak like that even on vehicles from the 60s to the 80s.
I have seen a brake pad get so worn out that it actually fell out of the caliper and still the piston (though overextended) never leaked!
As the guys in the thread have correctly pointed out to you, the only time you completely lose pedal like that is when there is a massive leak like the one you experienced or when the seals in the master cylinder have given way.
Probably a good idea to change all your brake hoses and rear brake cylinders (unless you have discs in the back) and have them flush the system with fresh brake fluid, now that you have the vehicle in the shop.
Preventative maintenance goes a long way and sometimes saves lives as well. With the inferior quality of parts that you have in India I think it's probably best to have the brakes inspected/serviced at least every two years if not every year. |
