Changan CS55 PLUS: Brake system warning light illuminated; check brake fluid and pads

Symptoms

• The brake system warning light is illuminated, or the brake fluid level is clearly below MIN. ^[1]

Possible causes

• The manual requires checking the fluid level when the warning is illuminated, and explains that brake pad wear can cause the level to fall slowly. A clearly low level requires diagnosis; do not infer caliper or master cylinder damage on this basis. ^[1]

Checks

• Check the level and this vehicle's specifications, and inspect in conjunction with brake pad wear. If the level is clearly below MIN, have the repairer diagnose it promptly; do not simply top up fluid and conceal the cause. ^[1]

What to do

• Follow the repair findings. Use new, clean brake fluid meeting this vehicle's specifications. Do not guess the fluid type or equate normal gradual wear with failure of a particular hydraulic component. ^[1]

Applicability and limits

• Official Russian-language owner's manual for Russia; CS55 PLUS; model years are not specified. No actual vehicle model has been linked. Scope: unknown ^[1]
• The cover and body identify CS55PLUS; the PDF metadata title incorrectly says CS95. The body takes precedence
• The preface date June 2021 is not treated as an applicable model year; do not extend to the first-generation CS55 or different generations of CS55PLUS
