2007 Kia Sportage Brakes Problems

Your brake pedal stopped responding when you pressed it while driving, even though no warning light came on. A mechanic found that your electronic brake control module had failed. This is a serious safety issue that requires the brake control module to be replaced by a qualified technician.

After having all wheel brake parts replaced, your brakes began freezing up on the driver's front and passenger's rear wheels within two weeks, making the car immobile. You had to manually release the frozen brakes using bleeder valves and the emergency brake to limp the car to the garage. When jacked up, the passenger rear wheel would lock whenever the brake pedal was pressed, and only opened when the bleeder valve was manually cracked. This issue appears to be related to the master cylinder leaking into the brake booster, which you replaced, but brake fluid still won't properly feed to the passenger rear brake to remove air from the system. The repair will likely require further diagnostic work on the brake system's master cylinder, brake booster, and brake lines to restore proper fluid pressure and bleeding.

Your brakes locked up completely while stopped at a red light, preventing the car from moving forward or backward even in neutral, and requiring a tow truck to move it. The front driver's side and rear passenger's side wheels wouldn't rotate at all. Based on online reports, this issue is caused by brake fluid leaking from the master cylinder into the power brake booster, which locks up the brakes and sometimes the transmission. The fix typically involves replacing the brake master cylinder and power brake booster.

Your ABS pump malfunctioned and caused all four brakes to lock up simultaneously, creating smoke and burning rubber while you were driving. You felt like the emergency brake was engaged and couldn't safely drive faster than 10 mph before the brakes completely locked as you pulled into your driveway. No warning light appeared on your dashboard to alert you to the problem. The fix will likely require ABS pump replacement or repair.
