We believe that flexible brake hose replacement is the most neglected chassis-related maintenance item on older Mercedes Benz. The combination of infrequent brake fluid changes and aging rubber can be death to these hoses - especially after 15 years - and it has nothing to due with the mileage of the car either. For those cars with ABS brakes, bad hoses, and old fluid can cause your ABS system to act up.
When these hoses break down, it usually begins internally. Deterioration is gradual and often not visibly apparent. The rubber inside the hose swells and breaks apart. This can create such a restriction in the flow of brake fluid that it can noticeably affect your braking. One brake caliper may end up applying more pressure to the rotor than the other. Deteriorated hoses can also act like a check valve. Fluid can be forced through to apply the brakes, but will not bleed off when the brake pedal is released. This can keep the pads pressing against the rotor longer than they should.
Common signs of hose trouble are brakes pulling the car to one side, premature brake pad wear, and in extreme cases - locking up and overheating of the brakes. You may also notice a spongy feel in your brakes if the hoses are rotted internally.
Changing these hoses is straightforward if you have the right tools and some knowledge of how to bleed your brakes once the hoses are replaced. You will need to remove your wheels, so plan to do the job when you are doing other brake or suspension work. You will need a 14mm open-end wrench to hold the hose from spinning but everyone should have that standard wrench in their tool kit.
