How can I tell if my Silverado 1500 has front brakes?

You can check with a multimeter to ensure you have the right amount of space between the sensor and wheel bearing but I just put one spacer on the sensor, bolt it back to the hib and spin my hub and liaten and feel for scraping. If u dont then put your caliper back on and test your brakes. Rust and corosion messes with the spacing for some reason

What to do when your disc brakes lock up?

Bled the brakes the next day and they did not improve. Heard a loud hiss coming from the booster and I replaced it and the master cylinder. Bench bled the master before installing it.
