Porsche Hydraulic Systems & Components
Your Porsche’s performance and safety rely on more than just the engine and brakes — the hydraulic system plays a vital role in delivering stopping power, smooth gear changes, and ride comfort. At Design911, we stock a full range of genuine and high-quality replacement hydraulic parts, including:
Brake hoses & lines Brake servos / boosters ABS pumps & modules Clutch master & slave cylinders Reservoir tanks & fluid containers Pressure accumulators Air suspension levelling componentsWhy
Hydraulics Are Essential
Hydraulic components use fluid pressure to
multiply force and deliver precision control. In your Porsche, this means:
- Braking power – consistent, responsive stopping through hoses, servos, and ABS pumps
 - Clutch control – smooth gear changes with accurate master/slave cylinder operation
 - System reliability – fluid reservoirs and accumulators keep hydraulic circuits primed
 - Comfort & handling – air suspension levelling maintains stability under varying loads
 
Without properly functioning hydraulics, your
vehicle’s safety, drivability, and performance are compromised.
Common
Faults & Warning Sign
Hydraulic parts wear out over time due to
heat, pressure, and age. Look out for these symptoms:
Brake Hoses
- Cracks, bulges, or fluid leaks along flexible lines
 - Spongy brake pedal feel
 - Uneven braking performance
 
Brake Servo / Booster
- Increased pedal effort required to stop the car
 - Hissing sound from the servo area (vacuum leak)
 - Poor braking response despite good pads/discs
 
ABS Pump / Module
- ABS warning light illuminated
 - Pulsating brakes under normal conditions
 - Loss of anti-lock function in emergencies
 
Clutch Master & Slave Cylinders
- Difficulty engaging gears
 - Pedal sinking to the floor or not returning properly
 - Fluid leaks around cylinders or reservoir
 
Reservoir Tanks
- Low fluid levels despite no obvious leak
 - Cracks or discolouration in plastic tanks
 - Contaminated or dirty hydraulic fluid
 
Pressure Accumulators
- Brakes feel hard or inconsistent
 - Hydraulic pump running excessively
 - Warning lights for brake pressure or suspension
 
Air Suspension Levelling
- Vehicle sits unevenly or drops overnight
 - Harsh ride quality or knocking sounds
 - Dashboard suspension/ride height warnings
 
Why Replace
Worn Hydraulic Parts
- Safety first – faulty hydraulics can lead to total brake or clutch failure
 - Performance – maintain the sharp response Porsche is known for
 - Preventative maintenance – replacing hoses, cylinders, and pumps early avoids costly damage to other systems
 - Comfort & control – ensure smooth ride height adjustment and braking stability
