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 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
