  If you're experiencing poor braking force with your TCM Forklifts, several factors could be at play. It might be due to brake fluid leaks, which require repair. Other potential causes include maladjusted brake shoe clearance (check and adjust the adjuster), overheating brakes (check for dragging), poor contact between the brake drum and lining (adjust contact), foreign matter sticking to the lining (repair or replace), foreign matter mixed in brake fluid (check brake fluid), or maladjustment of the brake pedal (adjust).

  If your TCM Forklifts exhibit a soft or spongy brake, it could stem from a few reasons. Start by checking for brake fluid leaks within the brake system and repair any leaks found. Also, inspect the brake shoe clearance and adjust the adjuster if it's maladjusted. Another possibility is air mixed in the brake system, in which case you should bleed the air. Finally, ensure the pedal is properly adjusted.

  Uneven braking in TCM Forklifts can arise from several issues. Check for foreign matter adhering to the lining, and repair or replace if necessary. Inspect and adjust the brake shoe clearance. A malfunctioning wheel cylinder might also be the culprit, requiring repair or replacement. Additionally, a defective shoe return spring should be replaced. Other potential causes include a deflected drum (repair or replace) or improper tire inflation pressure (adjust).

  A noisy brake in TCM Forklifts could be due to several reasons. The lining surface might be hardened or have foreign matter sticking to it, requiring repair or replacement. The backing plate could be deformed, or its bolts might be loose, also needing repair or replacement. Shoes might be deformed or improperly installed, necessitating repair or replacement. Other causes include unevenly worn lining (replace) or a defective wheel bearing (replace).
