I have. 2008 Dodge Ram 1500 that all 4 brakes lock up. The problem stated with spongy brakes so we replaced brakes ( yes bleed brakes) still had spongy brakes. Noticed that master cylinder was leaking so we replaced cylinder still had spongy brakes so replaced brake booster just in case leaking master cylinder caused problem with booster then all 4 brakes locked up had system bleed thought fixed problem didn’t have replaced master cylinder, brake booster, brakes twice and ABS module, brake calipers once and 4 gallons of brake fluid flushed thru system brakes still locking up. Have change fuses also. Any ideas as to why it’s still locking up
