Which Fortwo Cabriolet are you looking at?
Each Fortwo Cabriolet generation has its own weak spots. Pick the one you’re viewing to see what to check.
-
Brake hose deterioration and failure
Safety risk 450, 451MOT data shows Smart ForTwo cabriolets fail flexible brake hose inspections at 39.3 times the fleet average, primarily affecting 0.7L petrol variants. The brake hoses become excessively damaged, deteriorated, chafed, twisted or stretched at unusually low mileages. This affects the structural integrity of the brake hydraulic system and represents a critical safety risk. The issue appears to be worsening across the tested period 2020-2024.
What to check: Visually inspect all four brake hoses (rubber sections connecting brake lines to calipers) for cracking, bulging, or fraying of the outer rubber covering. Check for any signs of brake fluid weepage or staining around hose connections. Look for evidence of hoses rubbing against suspension componen...
-
Brake pipe corrosion
Safety risk 450, 451Smart ForTwo models show brake pipe corrosion and damage at 6.8 times the fleet average according to MOT data. The compact chassis design routes brake lines close to road spray and salt, particularly around rear suspension mounting points. Corroded brake lines represent an extreme safety risk as they can fail suddenly under braking pressure, causing complete brake system failure.
What to check: Inspect all visible brake lines under the car for surface corrosion, pitting, or flaking metal. Pay particular attention to mounting clips and bends where stress concentrates. Look for any brake fluid staining or wetness along the line routes. Check brake fluid level in reservoir - low level may ...
-
Engine mounting deterioration
Wear item 450, 451The three-cylinder engines in these cars generate significant vibration that accelerates rubber mount degradation. Failed mounts cause excessive drivetrain movement, gear selection issues, and potential damage to surrounding components.
What to check: Open the bonnet and visually inspect engine mounts for cracked, split, or separated rubber elements. Look for oil contamination on mounts which accelerates rubber deterioration. Check for obvious engine sag or misalignment in the bay.
-
Brake caliper binding
Safety and MOT risk 450, 451MOT testing reveals Smart ForTwo models show significant brake effort with no brake applied at 19.2 times the fleet average, indicating binding brake calipers. The compact brake system design and exposure to road salt accelerates caliper piston and slider pin corrosion. Binding brakes cause premature pad and disc wear, reduced fuel economy, and potential brake overheating.
What to check: Check each wheel for excessive brake dust accumulation which may indicate one brake is working harder than others. Feel each brake disc through the wheel spokes immediately after parking - one disc significantly hotter than others suggests binding. Look for any visible brake fluid leaks around ca...
-
Suspension component wear
Wear item 450, 451MOT data shows Smart ForTwo models suffer suspension bush and joint wear at rates significantly above fleet average. The compact suspension geometry places high loads on bushes and joints, particularly shock absorber bushes which fail at 10.7 times the fleet average. Worn suspension components cause handling deterioration, noise, and uneven tyre wear patterns.
What to check: Visually inspect suspension components for obviously split, cracked, or displaced rubber bushes. Check tyre wear patterns for inside or outside edge wear indicating suspension geometry problems. Look under the car for any suspension components hanging lower than normal or at unusual angles.
