Why these should be replaced:

Flexible rubber brake hoses age with heat, road grime and brake fluid exposure — they can dry-rot, crack, bulge or leak, creating an immediate safety hazard. Even without visible leaks, inner-liner deterioration or partial collapse can cause a soft/spongy pedal and uneven braking. Replacing old hoses with correct-fit OE hoses restores reliable pedal feel and prevents catastrophic fluid loss.

Common issues & failure modes:

• External cracking / dry rot from UV, heat and age — visible on inspection.
• Fluid leaks at hose body or end fittings due to perished rubber or corroded threads.
• Internal liner collapse (not visible) — causes restricted flow, delayed pressure build and a soft brake pedal.
• Mounting damage / chafing where the hose rubs against suspension parts — can wear through the outer cover and cause sudden failure. The OEM-style support/grommet helps prevent this.
