Normally I just search for things like this but this issue is specific enough that I can't seem to find someone who is having a similar enough issue to diagnosis it. It's weird enough in fact that a local indie is also stumped. So here it goes.
One day after normal driving I started up the car to the store, I instantly knew something was wrong because at the first stop sign the brake pedal became extremely hard once it was pushed down half way, like it feels normal until you hit halfway down and becomes insanely hard like trying to push bricks. The car also pulled dramatically to the right, I'm talking pulled the wheel out of my hands.
Naturally I limped the car home to pull the wheel off and see why the caliper was apparently stuck. Sure enough, pads out and pedal pushed there was no piston movement on the caliper. Thinking it was stuck I tried to compress the pistons with a C-Clamp expecting harsh resistance however they slid back into the caliper like butter. Upon pushing the brake pedal there was still no outward movement on the pistons. Thinking possibly that there was some-how dirt or air in the system I attached my bleeder tool to the caliper and had a friend pump the pedal with the valve open only to find out that absolutely no fluid was coming out of the valve.
At this point I was pretty sure maybe the soft-line had internally collapsed, and went about replacing it, only to find that after changing it out, there was still no fluid coming from the bleeder.
--
I took it to an indie because I was pretty stumped and he attempted force-bleeding the brakes, the other three calipers bled just fine however the driver front didn't bleed at all, even with the valve taken completely out of the caliper.
Carb cleaner has been sprayed on the area for the o-ring attaching the master cylinder to the booster as well as along the booster line and check valve. No hissing is present and the spray didn't effect the idle.
--
The only thing I can think of at this point is that somehow the booster is messed up, but then i'm confused why only one caliper isn't working and also as to why the pedal feels vacuum assisted until its halfway down. That or the Hard-line is somehow clogged but I don't even know how that would happen.
--
TL;DR:
My brake pedal feels hard halfway down and one caliper isn't working. Things done:
-Caliper compressed and inspected
-Soft-line replaced
-Force bled
-Vacuum tested
If anyone has any ideas or insight that would be great I'm pretty confused on this one .
