About 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 components

Why 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 firstfaulty hydraulics can lead to total brake or clutch failure
  • Performancemaintain the sharp response Porsche is known for
  • Preventative maintenancereplacing hoses, cylinders, and pumps early avoids costly damage to other systems
  • Comfort & controlensure 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.
