Default H3 left brake locked up..tc and abs light on

Over the past couple weeks the tc and abs light has been going off and on.. Sometimes when I would hit the brakes it would almost lock up just on the left front wheel and when I’d let go of the brake it’d release..happening several times over the course of the 2 weeks.. Today on the other hand it completely locked up and wouldn’t release for a couple seconds and the tc light was flashing and wouldn’t hardly pull like it was in limp mode?????

This is all just gibberish... Lol!

Codes?
Year, make, model??
Miles???

The traction control and abs codes will take an advance code reader or tech 2.

Sounds like a failed/failing ABS wire or sensor.

Year, Model & Miles and recent work should all be included when asking members to pitch in on diagnosing your issue.

LOOK at the wiring to the ABS hub sensor and the connector for the wheel in question. Frayed insulation, dirty or loose connector are the easy stuff.

If the brake isn't releasing right away I would suspect the caliper is seizing. Replace the caliper, about $100 depending on manufacturer.

Loose or worn wheel bearing also causes problems with ABS/Traction and brakes. Have the two front wheel bearings checked for play and noise.
