1. Parking Brake: This is the most obvious and easiest to check. Make absolutely sure the parking brake is fully released. A partially engaged parking brake is a very common cause of dragging brakes.
2. Caliper Piston Sticking: This is a very frequent problem. The caliper piston might be corroded or seized, preventing it from retracting fully. This can be caused by:
* Rust and corrosion: Salt, moisture, and time take their toll.
* Dirt and debris: Contaminants can build up and interfere with piston movement.
* Damaged piston seals: Damaged seals allow brake fluid to leak past the piston, leading to sticking.
3. Caliper Slide Pins (or bushings): The caliper slides on pins (or in bushings) which allow it to squeeze the rotor. If these pins are seized or corroded, the caliper can't move freely, leading to the pads remaining in contact with the rotor.
4. Brake Hose Issues: A kinked or partially blocked brake hose can prevent proper fluid return to the master cylinder, keeping pressure on the calipers and preventing release.
5. Master Cylinder Issues: While less likely to cause *only* the front brakes to drag, a failing master cylinder could contribute to the problem. It might not be returning fluid properly, or it could have internal issues.
6. Vacuum Booster (if equipped with power brakes): A failing vacuum booster could reduce braking assistance, potentially contributing to the feeling that the brakes are dragging. However, this is more likely to present as weak brakes rather than just dragging ones.
7. ABS System (if equipped): While less common, an issue within the anti-lock braking system (ABS) could theoretically contribute. This would be a more complex diagnosis and would require specialized tools and knowledge.
How to Diagnose:
1. Start with the parking brake. Ensure it's completely released.
2. Visually inspect the calipers: Look for rust, corrosion, or anything unusual around the caliper pistons and slide pins. Try to gently move the calipers by hand – they should slide relatively easily.
3. Check the brake hoses: Inspect them for kinks, bulges, or damage.
4. Feel the calipers and rotors after a drive: After driving for a short distance, carefully touch the calipers and rotors. If they're excessively hot, it indicates dragging brakes. Compare the temperature difference between the affected and unaffected sides.
5. Check brake fluid level: Low level could indicate a leak.
If you're not comfortable working on brakes yourself (it's strongly recommended to have experience and proper tools), take your Dodge Dakota to a qualified mechanic. Brake issues can be dangerous if not addressed properly.
