How do I fix the front brake line on a Hyundai Tucson 2006

if it is locked up on the front left side only , it sounds like the caliper is stuck , remove caliper and see if you can squeeze it in with a large c clamp .. may be hard to remove if it is stuck on caliper . replace with rebuilt if it is locked up then rebleed

bleeding the brakes can be done manually with the help of another person. have your helper pump the brakes and hold the pedal until you release the bleeder enough to get air or fluid flowing and then shut off. you can then tell the helper to pump again but only after you have closed the bleeder. do this two times on each wheel starting with the wheel in the rear furthest from the master cylinder. then the other rear wheel then the front wheel furthest from the master cylinder and finally the other front wheel. you should get a better pedal each step. don't let the master cylinder reservoir run dry during this procedure.

I believe the adjuster nut is up under the brake handle itself.
Not easy to get at .

Best case scenario bad vacuum pressure to the brake booster. Worst case bad abs control module or valve body/motor the abs system works by add and removing hydraulic pressure through valves and electric motor. Try using block off plugs at the master cylinder( remove lines plug outlets at master cylinder) check if brake pedal position and pressure is good(if there is no change problem is master cylinder or brake booster/ vacuum) if plugging at master cylinder solved issue repeat procedure at abs valve body after reinstalling lines from master cylinder if your problem returns your issue is in the abs valve body if plugging at the abs solves problem reconnect at the valve body bleed each line one by one testing between each line until you find the problem

be looking at the brake pedal switch and also control module tho I think that gets tested at the dewaler..

1 check you fuse if not that then check the bulbs in each light

they may look similar but u should use the proper fluid or risk damage

rear pad replacement is basically the same as front. 14mm bolts holding caliper and mount on hub then the piston just pushes in

yes they can be just pushed in

Hve you had the brakes checked. Sounds like the brakes are grinding
