Why Does My Car Shake When Braking? Causes and Solutions in Montana Park

Understanding Brake Shudder

Have you ever stepped on the brake pedal only to feel a violent shudder through your steering wheel or the seat? This sensation, often referred to as brake shudder, is a common issue that vehicle owners face. In this guide, we will look at the primary causes of this issue and how to resolve it.

1. Warped Brake Discs (Rotors)

The most common cause of shaking when braking is warped brake discs. When you brake, the brake pads are pressed against the discs to slow the vehicle. This creates immense heat. Over time, rapid heating and cooling cycles, or driving through water when the brakes are extremely hot, can cause the metal discs to warp. When the pads press against a warped surface, it results in a pulsating feedback.

2. Uneven Brake Pad Deposits

Sometimes, the disc is not physically warped, but instead has accumulated uneven deposits of brake pad material. If you hold the brakes down firmly after a hard stop, the hot pad can transfer material onto a single spot on the disc. This creates high and low spots, leading to steering wheel vibration when braking.

3. Worn Suspension Components or Wheel Bearings

A worn steering link, loose bushing, or damaged wheel bearing can amplify minor brake disc variations, causing the vehicle to shake. If your suspension is loose, the normal braking forces can cause components to oscillate.

How BSR Resolves Brake Shudder

At BSR Fitment Center in Montana Park, Pretoria, we perform a digital safety inspection to find the exact cause. If the discs are within manufacturer minimum thickness specifications, we can perform precision on-car disc skimming to restore a perfectly smooth braking surface. If they are too thin, we replace them with high-quality OEM discs and pads.
