Why does the steering wheel pull to the side when braking and how to fix it?

• After braking, touch the rims with your hand (be careful, they are hot!). If one wheel much hotter the other - the caliper has turned sour.

For a more accurate diagnosis, you can use diagnostic scanner (for example, Launch CReader or ELM327), if your car supports error reading by ABS. Fault codes C0035–C0050 often indicate problems with the wheel speed sensors, which can also cause wheel slip.

Brake system: most common faults

In 60% of cases, the brake system is to blame. Let's consider three key issues and ways to eliminate them:

1. Soured caliper or guides

If the caliper does not release after braking, the pad continues to rub against the disc, resulting in overheating and uneven braking. Signs:

• One wheel after a trip hot to the touch.
• Heard extraneous noise (creaking or humming) when moving.
• The brake pads on one wheel are wearing out. 2–3 times faster.

How to fix:

1. Remove the caliper and clean the guides of rust and dirt (use WD-40 or special grease for calipers, for example, SLIPKOTE 220-R DBC).
2. Check the guide boots - if they are torn, replace them.
3. If the caliper piston does not move freely, you will need to caliper repair or replacement.

2. Warped brake discs

The discs “drive” due to a sharp temperature change (for example, after aggressive braking followed by getting into a puddle) or mechanical damage. How to check:

• When braking you feel pulsation on the pedal.
• Visible on the disk blue spots (overheating) or deep furrows.
• When you turn the disk by hand you feel beating.

Solution:

• If the disk “drives” slightly (runout up to 0.1 mm), it can be turned on a machine.
• In case of severe deformation (runout more than 0.15 mm) or cracks - only replacement.
• After replacing disks necessarily Replace the pads too, even if they seem to be working!

3. Faulty brake hoses

Rubber hoses crack over time or the inner layer peels off, blocking the reverse flow of brake fluid. This results in the pads not moving away from the disc. Signs:

• The brakes “stick” after pressing the pedal.
• Cracks or fluid leaks are visible on the hoses.

What to do:

• Replace the hoses as a pair (even if only one is faulty).
• After replacement bleed the brake system.

The influence of suspension and wheel alignment on steering shift

If the brake system is in order, but the car still pulls when braking, the problem may lie in suspension or incorrect wheel geometry. Let's look at the key points:

1. Wear of silent blocks or ball joints

Over time, the silent blocks of the suspension arms “get tired” and lose elasticity, and the ball joints become loose. This leads to changing wheel alignment angles and, as a result, drift when braking. How to check:

• Jack up the car and rock the wheel with your hands in the vertical and horizontal planes. Play of more than 1–2 mm is a sign of a malfunction.
• Inspect the silent blocks for cracks or peeling rubber.

Solution:

• Replace worn silent blocks or ball joints (preferably in pairs on the same axis).
• After replacement necessarily do a wheel alignment.

2. Incorrect wheel alignment

Even if the suspension is working properly, incorrect wheel alignment angles can cause wheel slip. Signs:

• The car is pulled to the side not only when braking, but also when driving in a straight line.
• Uneven tire wear (for example, “eating” the inside or outside of the tread).

What to do:

• Perform wheel alignment adjustment on 3D stand (cost - from 1,500 rubles).
• If the problem persists after adjustment, check body geometry — the car may have been in an accident.

The influence of tires and pressure on traction when braking

Sometimes the problem lies not in the mechanics, but in tires or pressure. Here's what to check:

• 🔄 Different tire pressures: Even a difference of 0.2–0.3 atm can cause drift. Check with a pressure gauge and equalize the pressure according to the manufacturer's recommendations (usually indicated on a sticker in the doorway).
• 🛞 Uneven tread wear: If one tire is bald and the other has normal tread, the grip on the road will be different.
• 🔀 Different tire models on the same axle: Never put tires of different brands, models or with different levels of wear on the front or rear axle.
• 🌀 Wheel imbalance: If the wheel is unbalanced, vibration and slight slip may occur when braking.

Critical point: if your car has directional tires (for example, Nokian Hakkapeliitta or Michelin Pilot Sport), make sure they are installed in the correct direction of rotation. The wrong direction can cause you to pull when braking, especially on wet roads.

How to check:

1. Inspect your tires for uneven wear (such as saw-tooth tread).
2. Check the pressure in all wheels (should be the same on one axle).
3. If your tires have recently been replaced, make sure they are properly balanced.

When to contact a car service: signs of serious problems

Some problems cannot be fixed on your own. Urgently go for diagnostics, if:

⚠️ Attention: If when braking the car skids a lot or steering wheel jerks sharply to the side, this could be a sign brake circuit failure or breakdown of the brake master cylinder (brake master cylinder). Operate the vehicle in this condition prohibited!

• 🚨 Brake pedal fails or becomes “cotton”.
• 💦 Appear under the car puddles of brake fluid.
• 🔴 Lights up on the dashboard ABS lamp or brake system icon.
• 🛠️ Problem after replacing brake discs or pads intensified.

The car service center must:

1. Computer diagnostics brake system (checking sensors ABS, pressure in the circuits).
2. Checking the tightness brake lines.
3. Suspension diagnostics on the lift (play, condition of silent blocks, steering rods).

The average cost of comprehensive diagnostics in Moscow is: 2,000–4,000 rubles. But it's better to overpay for an inspection than to risk your life because of faulty brakes.

Prevention: how to avoid steering wheel pull when braking

To prevent the problem from returning, follow these recommendations:

• 🔧 Every 10,000 km check the thickness of the brake pads and the condition of the discs.
• 🛠️ Once every 20,000 km lubricate the caliper guides with special lubricant (for example, TRW PFG110).
• 🌀 Every 15,000 km do wheel balancing.
• 📏 Once every 30,000 km or after repairing the suspension, adjust the wheel alignment.
• 🚗 Avoid aggressive braking at high speed - this leads to overheating of the disks and their deformation.

What not to do:

⚠️ Attention: Never “break in” new brake pads by aggressive braking at high speeds. This leads to uneven wear and overheating of disks. Proper grinding is several smooth braking from a speed of 60–80 km/h.

If you frequently drive off-road or in wet conditions, increase the frequency of checks braking system. Dirt and water accelerate corrosion of calipers and discs.
