Hard brake pedal

[rreegg]

brake system status: the rabs and parking brake light have been coming on the past 10 days or so. topped off brake fluid and seem to have caught a small leak at back left wheel cylinder. haven't bothered to check brake codes yet but at the least gotta replace wheel clinders with known 3", will probably replace shoes too but leave drums..

Brake leaks are one of those things that you don't want to procrastinate on. Especially with winter coming on. I've done brake work in the winter, outside before. It's NOT fun.

every season is brakework season on this truck, hope to change that though

I refuse to drive a vehicle with leaking brakes. Unless I have to limp it home, and won’t have to go through any towns. Then I might make an exception. But I would never willingly drive a vehicle with leaking brakes.

brakes have been great after rebuild, parking brake seems to hold well after not many clicks. no leaks and solid consistent brake feel.

finally able to diagnose the parking brake and rabs lights being on and it's code 4 - RABS valve switch closed or open dump valve. have done some reading and someone mentioned the master cylinder electrical connection being relevant here.

the brake mc connector, on the truck side electrical harness has been weak and come off the wires a few times. anyone know where/if i can get a replacement connector? might need to be a pnp trip

basically same issue as this https://www.therangerstation.com/fo.../brake-master-cylinder-plug-connector.195512/ looks like part number wpt-1001 from motorcraft
