Kia Troubleshooting Questions? Ask a Mechanic
Welcome, I'm Chris (aka Moose).
Are you able to do electrical diag for the tachometer issue and brake repairs?
Do you have rear disc or drum bakes?
If the parking brake is not to blame then you have a faulty wheel cylinder or calipers or the brake pad mounting hardware is damaged allowing the brakes to shift and bind.
If you're confused on what to do now. You have already been charged the full question value. It's now time to compensate the tech that helped you. The only way I can continue to work here and help customers is by getting rated. If you're not pleased yet or plan not to rate me. Let me know so I can help more, close the post, or opt out. Please let me know if you're pleased with my help.
Hello again Chris here,
