Car Pulls to One Side When Braking - 2016 Lancer ES

Vehicle: 2016 Mitsubishi Lancer ES

Hi everyone,

I've got a problem with my 2016 Mitsubishi Lancer ES. Lately, whenever I apply the brakes, the car pulls noticeably to the left. It's not a gentle drift; it's a definite tug that I have to correct with the steering wheel. It doesn't pull when I'm just driving normally, only when braking.

I'm concerned this could be a serious brake issue. I had the front brakes replaced about a year and a half ago, but the rear brakes are original. Could it be a stuck caliper, or something else entirely? I'm trying to get an idea of what I might be looking at before I take it to a mechanic.

Thanks for any advice!

ClearTheCode admin answer:

A vehicle pulling to one side specifically during braking is a classic symptom of an issue with the braking system on the opposite side of the pull. Since your 2016 Mitsubishi Lancer ES pulls to the left, the problem is likely with the right-side brake (either front or rear) not engaging properly, or the left-side brake grabbing too hard.

  1. Most Common Causes for Pulling During Braking:

    • Stuck/Seized Caliper: This is a very frequent cause. If a brake caliper on one side (e.g., the left side) is seizing, it will apply more pressure than the other side, causing the car to pull towards the side with the grabbing brake. Conversely, if a caliper on the opposite side (e.g., the right side) is not engaging at all, the car will pull towards the side that is braking effectively.
    • Collapsed/Restricted Brake Hose: A rubber brake hose can internally collapse or become restricted, preventing brake fluid from reaching the caliper on that wheel. This reduces braking force on that side, causing the car to pull to the opposite side.
    • Uneven Brake Pad Wear: If brake pads on one side are significantly more worn or contaminated than the other, it can lead to uneven braking force.
    • Air in Brake Lines: Air in the brake lines can cause a spongy pedal and uneven braking, though it's less likely to cause a consistent pull to one side.
    • Wheel Bearing Issues: While less common to cause a braking-specific pull, a severely worn wheel bearing can affect how the wheel interacts with the braking system.

  2. When to See a Shop:

    • Immediately: Any issue that causes your vehicle to pull significantly during braking is a serious safety concern. It can compromise your ability to maintain control, especially in an emergency stop. Do not delay in getting this inspected.

What a Shop Will Do:

  • Thorough Brake Inspection: They will inspect all four wheels, checking the calipers, pads, rotors, and brake hoses for signs of wear, damage, or malfunction.
  • Check for Seized Calipers: They will manually check if the calipers are moving freely and if the pistons are retracting properly.
  • Inspect Brake Hoses: Look for any swelling, cracks, or signs of internal collapse.
  • Bleed Brake System: If air is suspected, they will bleed the brake lines.

Given the safety implications, it's crucial to have a qualified mechanic diagnose and repair this issue as soon as possible.
