Overview
This article addresses the issue of brakes grabbing on telehandlers. Brake grabbing refers to a situation where the brakes engage abruptly or unevenly, causing jerky movement, difficulty controlling the machine, or excessive wear on braking components. Understanding the causes and remedies of this problem is essential for safe operation and equipment longevity.
Common Causes of Brake Grabbing
Brake grabbing on telehandlers typically results from contamination, worn parts, improper adjustment, or hydraulic system problems. Effective troubleshooting includes cleaning, inspecting, adjusting, and repairing brake components and hydraulic elements. Proper maintenance and timely repairs can resolve grabbing issues, enhancing operator control and safety.

Common Causes of Brake Grabbing
- Contaminated Brake Surfaces
Dirt, oil, or grease on the brake discs, drums, or pads can cause uneven friction and lead to grabbing.
- Worn or Damaged Brake Components
Brake pads, shoes, or discs that are excessively worn, cracked, or warped can result in uneven braking force and grabbing.
- Improper Brake Adjustment
Incorrect adjustment of brakes can cause some brake shoes or pads to engage sooner or harder than others, causing grabbing.
- Hydraulic System Issues
Problems with the hydraulic brake system, such as sticking calipers, uneven pressure, or air trapped in the lines, can cause grabbing.
- Faulty Brake Calipers or Cylinders
If calipers or wheel cylinders are sticking or malfunctioning, brakes may grab unexpectedly.
- Inspect brake surfaces for contamination and clean if necessary.
- Check wear levels of brake pads, shoes, discs, and drums.
- Verify proper brake adjustment according to manufacturer specifications.
- Examine hydraulic lines and components for leaks, damage, or air bubbles.
- Test calipers and cylinders for smooth operation without sticking.
- Thoroughly clean brake components to remove any contaminants.
- Replace worn or damaged brake parts promptly to ensure even braking.
- Adjust brakes carefully following the telehandler’s service manual guidelines.
- Bleed hydraulic brake lines to remove trapped air and restore consistent pressure.
- Repair or replace faulty calipers or wheel cylinders to ensure proper movement.
- Regular inspection and maintenance of the braking system prevent grabbing and ensure safe operation.
- Avoid using the telehandler on rough terrain with brakes that grab, as this can cause further damage.
- Consult qualified technicians if the grabbing issue persists after basic troubleshooting.
