Trying to save myself an expensive trip to the mechanic.
Front brakes stick especially after driving more than 5-10 minutes, at times they will grab so hard the car will barely move. They will release after an extended period of time though. 5-30 minutes depending on how stuck they were.
cannot get fluid to rear brakes, yes I’ve used a vacuum bleeder.
Front has new pads new rotors and new driver side caliper.
i do not have any brake lights on the dash. So im assuming the abs module and pump is fine.
Ive tried fiddling with that bleeder on the abs pump I believe it is and wasn’t able to get anything out of it.
took a peep into the abs module. The fluid appears to be darker than the rest of my fluid. Indicating it hasn’t cycled through any new fluid in a long time.
a trusted mechanic here said it is likely my ABS pump although it doesn’t make sense as a light should pop up regardless if any of those are bad.
maybe a stuck valve that needs to be freed up?
what steps should I take to get fluid to these rear brakes?
yes im getting fluid out of the master directly to the rear line. The master looks newer as well.
booster not sure havnt tested it.
brake pedal after starting car is soft at first, then gradually becomes firm as the brakes begin to stick.

Probably a bad master cylinder. My parents 01' Sienna had a MC failure and it would almost lock up both front brakes after a short drive and wouldn't release after a stop.

master should be okay it does look to be on the newer side. I’m getting fluid out of the master to the rear lines. Fluid was very dirty indicating no flow. Cracked line to rear brakes off of the proportioning valve and it was bone dry!! Does anyone know how I can reseat the valve properly, or how I would go about this, because man I can’t find a porp valve anywhere online. Nor are there any parts cars in my area let alone state lol.
