Measuring 91mm in length with 17mm and 22mm end diameters, this direct replacement boot is an important but often overlooked component within the mechanical throttle linkage assembly used on classic air-cooled Porsche 911 models.

As rubber components age, they can crack, split and lose flexibility, allowing contaminants to enter the linkage system and accelerate wear. Replacing worn boots helps preserve the smooth and precise throttle response that Porsche intended.

What Does the Accelerator Rod Boot Do?

The accelerator rod boot acts as a protective seal around the throttle linkage assembly.

Its primary functions include:

• Protecting the accelerator rod from contamination
• Preventing dirt and debris ingress
• Keeping moisture away from linkage components
• Helping preserve smooth throttle operation
• Protecting linkage bushes and joints
• Reducing wear within the throttle mechanism
• Extending component lifespan

Although small, the boot helps safeguard critical throttle linkage components from premature wear.

Why Do Accelerator Rod Boots Fail?

The boot is constantly exposed to harsh operating conditions beneath the vehicle and within the engine compartment.

Common causes of deterioration include:

• Age-related rubber hardening
• Heat exposure
• Oil contamination
• Road debris
• Moisture exposure
• UV ageing
• Ozone damage
• General wear and tear

Over time, the rubber loses flexibility and can develop cracks or splits.

Symptoms of a Worn Accelerator Rod Boot

Common signs of deterioration include:

• Cracked rubber
• Split boot material
• Missing sections of rubber
• Visible dirt around linkage components
• Increased linkage wear
• Stiff accelerator operation
• Excessive play within the throttle linkage
• Deteriorated engine bay appearance

Many damaged boots are discovered during routine servicing or restoration work.

When Should the Accelerator Rod Boot Be Replaced?

Replacement is recommended when:

• Cracks or splits are visible
• The boot has hardened or perished
• Throttle linkage components are being serviced
• Carrying out a restoration project
• Replacing throttle linkage parts
• Engine-out maintenance is being performed
• Preventative maintenance is being undertaken

Because of its low cost and important protective role, replacement is often recommended whenever the linkage system is disassembled.

Why Replacement Matters

Replacing a deteriorated accelerator rod boot helps protect the entire throttle linkage assembly.

Benefits include:

• Improved linkage protection
• Reduced dirt and moisture ingress
• Longer component lifespan
• Smoother throttle operation
• Improved reliability
• Reduced maintenance costs
• Better engine bay presentation

Diagram ref no 19

The brake pedal return spring is an important part of the pedal assembly, helping maintain smooth, consistent pedal movement and ensuring the brake pedal returns correctly when released.

Over time, the original spring can weaken, corrode, stretch or break, potentially resulting in sluggish pedal return, excessive pedal movement or an incorrectly positioned brake pedal.

Replacing a worn or damaged spring helps restore the intended operation of the brake pedal assembly and contributes to the safe and reliable functioning of the braking system.

What Does the Brake Pedal Return Spring Do?

The brake pedal return spring assists the brake pedal in returning to its normal resting position when the driver releases pressure from the pedal.

Working alongside the pedal linkage and brake master cylinder mechanism, the spring helps maintain consistent pedal movement and return action.

Its main functions include:

• Assisting the brake pedal's return to its resting position
• Maintaining the correct pedal return action
• Helping prevent excessive pedal movement
• Supporting smooth operation of the pedal assembly
• Contributing to consistent brake pedal feel
• Helping maintain the correct relationship between the brake pedal and its associated controls

Although relatively small, the return spring is an important mechanical component within the brake pedal assembly.

Why Does the Brake Pedal Return Spring Fail?

Brake pedal return springs are subjected to repeated tension and movement every time the brakes are applied.

After many years of use, the spring may lose its original tension or suffer mechanical damage.

Common causes of failure include:

• Metal fatigue from repeated pedal operation
• Corrosion caused by moisture and age
• Loss of spring tension over time
• Stretching or deformation
• Breakage caused by excessive loading
• Incorrect installation during pedal assembly repairs
• Damage to the spring's mounting or attachment points

A weakened or broken spring may no longer provide sufficient assistance to return the brake pedal correctly.

When Should It Be Replaced?

Replacement is recommended whenever the brake pedal return spring becomes weakened, stretched, corroded, damaged or broken.

Common symptoms include:

• Brake pedal slow to return after being released
• Brake pedal failing to return fully to its resting position
• Excessive free movement in the pedal assembly
• Unusual pedal movement or inconsistent return action
• Visible corrosion or deformation of the spring
• Broken or missing spring Incorrect pedal positioning following previous repairs

The return spring should also be inspected during pedal cluster refurbishment, brake master cylinder replacement or a complete classic Porsche restoration.

A brake pedal that does not return correctly may also indicate a fault elsewhere in the braking system and should be investigated before the vehicle is driven.

Checks & Diagnosis

Before replacing the spring, inspect the complete brake pedal assembly to determine the cause of the problem.

Check for:

• Weak, stretched or broken return spring
• Corrosion around the pedal pivot points
• Worn pedal bushes or bearings
• Stiff or seized pedal movement
• Damaged spring attachment points
• Incorrect pedal linkage adjustment
• Brake master cylinder or pushrod problems
• Obstruction preventing full pedal return

A sticking brake pedal is not always caused by the return spring. Binding pedal pivots, incorrect linkage adjustment or hydraulic faults can produce similar symptoms.

If the pedal does not return fully or the brakes remain partially applied, the underlying fault must be identified and repaired.

Installation Notes

The brake pedal return spring is fitted within the brake pedal assembly and should be installed in accordance with the Porsche workshop instructions.

Before installation, inspect the pedal pivots, bushes, spring mounting points and associated linkage for wear or damage.

Ensure the replacement spring is correctly positioned and securely attached.

Take care when fitting or removing the spring, as it may be under tension.

After installation, check that the brake pedal moves freely and returns fully to its correct resting position.

Verify the brake pedal free play, brake light switch operation and correct brake release before returning the vehicle to service.

Professional installation is recommended because the component forms part of the braking system.

Manufactured to match the original equipment dimensions and fitment, this kit contains seven plastic bushings for the brake pedal, clutch pedal, accelerator bell crank and clutch clevis pin assemblies.

The pedal box is an essential part of the vehicle's control system, allowing the driver to operate the brakes, clutch and accelerator. Each pedal relies on correctly fitted bushes to maintain smooth pivoting movement, proper alignment and consistent mechanical operation.

The pedal bushings provide low-friction bearing surfaces between moving components, helping reduce metal-to-metal contact, minimise unwanted movement and maintain the correct positioning of the pedal shafts and linkages.

Over time, original plastic bushings can deteriorate due to ageing, repeated pedal operation, friction, moisture and general wear. Worn or cracked bushes may develop excessive clearance, resulting in loose pedals, squeaking noises, inconsistent pedal movement or difficulty returning to the normal resting position.

A seized or deteriorated accelerator linkage bush may also cause throttle movement to become stiff or inconsistent, while worn brake and clutch pedal bushes can contribute to unwanted pedal movement and reduced precision.

Replacing the original worn bushes with the OE MATCH Pedal Bushing Kit helps restore the factory-style pedal mechanism, improve pedal alignment and support consistent brake, clutch and accelerator operation.

Ideal for classic Porsche maintenance, pedal box refurbishment, clutch pedal repairs, brake pedal servicing and complete vehicle restoration projects.
