Hydraulics
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
Design911 stocks OEM and performance hydraulic components for every Porsche model. Whether you need a simple brake hose replacement or a complete ABS pump, our range ensures your Porsche remains safe, responsive, and enjoyable to drive.
