subaru wrx type ra. lately since the snow my brakes have become really stiff with my car stoping very sudden after taking foot off acceleration. also brakes did not work and there was no air pressure when braking an nealry caused me to crash by skidding. any ideas what this is. also front rear brake dis/pads are really hot after driven
very weird combination of symptoms. the stiff pedal is beyond me but if it's cold related i'd think you have a valve or hose for the brake booster getting frozen/stuck from cold/ice. remove, clean out, spray down with WD40 i think will repel the moisture, but i've only heard it and haven't had to do it yet.
heat....usually means pads are dragging - often caused by ungreased or rusty slider pins...particularly in the rust belt.
really bad wheel bearings can generate heat too.
with enough dragging or heat - your brake fluid could boil and loose brake pressure.
hoses can collapse too, causing the calipers to grab but not retract - making for constant braking/heat - but Subaru's aren't know for that, i've never seen it on a Subaru yet.

which brakes are hot...you said "front rear"....meaning all 4- that doesn't make sense.

Sounds like a master cylinder failure on the first stage. Second stage in the master cylinder makes the pedal travel farther and feel hard. You can still get enough brake pressure if you mash on it hard enough. No air in the brakes sorry at least proper brakes that is.
It does sound like the master cylinder has failed due to the temp. This is a known problem in Outbacks. Subaru Outback Brake Master Cylinder Problems
Just wondering when was the last time you changed your brake fluid? It should be no more than 2 years.
