I just LOVE those unschiduled lane changes when you step on the brakes,
And again when you let off the brakes!
It's pulling towards the brake that IS working.
If it tries to spin the steering wheel, it's a front brake.
If it just drifts towards the ditch or curb, it's probably a back brake.
Where I would start...
1. Check your master cylinder.
When you get low on brake fluid, one brake will stop getting fluid before the other, so you get a sideways dart.
2. Anytime you do brakes, you MUST start in the REAR!
Make sure your rear brakes are adjusted up, they have pad material on the Shoes, and there aren't any leaks.
3. Once the back brakes are checked/adjusted,
Move to the front.
Inspect ALL LINES FOR LEAKS! Front and Rear.
Then check the caliper on the LEFT SIDE.
Take it off the rotor, pump the brakes, see if the piston is working.
Be sure to leave the pads in place so you don't shoot the piston out of the caliper, which would be BAD.
Sometimes, the pistons get rusted into the bores, and they won't move.
Check pads, make sure they aren't shot.
Check rubber lines, look for leaks, cracks, ect.
A rubber line CAN degrade internally.
I've seen them NOT pass brake fluid they are so damaged internally...
If the rubber is cracked, or they are more than about 10 years old, CHANGE THEM.
When you are done with visual inspection, try bleeding the fronts, stating with left side, see if you get any air bubbling up out of the bleeder.
If you find air, then you have a leak.
Start looking for a line leak or leak at the piston seals.
The fact that you have ONE front brake working means your master cylinder is doing it's job, so it's probably NOT the master cylinder,
But I suggest you pull the carpet back, look INSIDE the vehicle, and between booster and master cylinder for fluid leaks.
Often times, when something goes, the rest of the system isn't in good shape either...
Mudding usually isn't a factor, other than to pack mud in everywhere you want to inspect now...
Mud is hard on pads, rotors, wheel seals, ect.
But it usually doesn't effect the brake calipers.
Since you use the brakes before the mud dries solid, it's usually pushed out of the way and doesn't effect the brake function.
Mud and Rust can effect the ability of the pads to move in the caliper,
And the caliper to move on the caliper mount, so while you are there, don't forget to use 'Never-Seize' on the moving parts of the brake brackets/caliper when you re-assemble. (Just keep it off the pad faces and rotor!)
