Installed around the parking-brake cable, the spacer tube helps keep the cable correctly positioned and aligned as it runs between the handbrake mechanism and the rear brake assemblies.

Correct cable routing is important for smooth handbrake operation and helps prevent the cable from rubbing, bending excessively or moving against surrounding components.

This OE Match replacement is ideal for replacing an original spacer tube that has become corroded, bent, cracked, damaged or missing.

What This Product Does:
The handbrake, or parking brake, uses mechanical cables to transfer movement from the handbrake lever to the rear parking-brake mechanism.

The spacer tube supports and guides the cable along its intended route.

Its functions include:

• Helping maintain correct handbrake cable alignment
• Supporting the cable along its routing
• Preventing excessive cable movement
• Reducing rubbing against surrounding components
• Helping protect the cable from premature wear
• Maintaining correct spacing within the handbrake assembly
• Supporting smooth handbrake application and release
• Helping preserve the original factory cable routing

One spacer tube is typically used per handbrake cable, meaning two may be required per vehicle depending on application.

Symptoms Of Wear Or Failure:
The spacer tube is exposed to road contamination, moisture, vibration and age-related deterioration.

Common signs that replacement may be required include:

• Visible rust or corrosion
• Bent or distorted tube
• Cracks or physical damage
• Missing spacer tube
• Excessive movement of the handbrake cable
• Cable rubbing against surrounding components
• Handbrake operation feeling rough or inconsistent
• Increased resistance when applying the handbrake
• Cable not returning smoothly when released
• Rattling or movement underneath the vehicle
• Premature wear or marking on the handbrake cable
• Difficulty routing a replacement handbrake cable correctly

A stiff or ineffective handbrake can also be caused by seized cables, worn shoes, incorrect adjustment or damaged linkage components, so the complete system should be inspected.

Why Replacement Matters:
The handbrake cable must follow the correct route and move freely for the parking-brake system to operate properly.

If the spacer tube becomes bent, damaged or missing, the cable may move out of position or rub against surrounding components. This can increase friction and accelerate wear of the cable outer casing.

Incorrect cable routing may also make the handbrake feel stiff or inconsistent and can interfere with smooth release of the parking brake.

Replacing a damaged spacer tube helps restore:

• Correct handbrake cable routing
• Proper cable alignment
• Reduced friction and unwanted movement
• Smooth handbrake operation
• Protection against premature cable wear
• Correct factory-style installation

For restoration projects, renewing deteriorated spacer tubes at the same time as the handbrake cables helps ensure that the complete mechanical parking-brake system is correctly supported.

Handbrake Cable.

The OE Match Handbrake Cable is a replacement mechanical parking-brake cable for selected classic Porsche 911 SC and Carrera models from 08/1977 to 07/1989.
Length: 1413 mm

Fits:

• Porsche 911 SC/Carrera 2.7-3.2 08/77-07/89

Diagram Ref No 45

Measuring approximately 1413 mm in length, the cable connects the handbrake mechanism to the rear parking-brake assembly, transmitting the driver's pull on the handbrake lever to the brake shoes at the rear wheels.

Two parking-brake cables are normally used on the vehicle, one operating each rear wheel, so replacement in pairs is often advisable where both original cables are of similar age.

What This Product Does:
The handbrake cable mechanically transfers movement from the handbrake lever to the rear parking-brake mechanism.

When the handbrake lever is pulled:

• Tension is applied to the cable
• The cable pulls the parking-brake operating mechanism
• The rear parking-brake shoes expand
• The shoes grip the internal braking surface
• The rear wheels are mechanically held

When the lever is released, the cables and brake return springs allow the parking brake to disengage.

The cable therefore provides the physical connection between the driver's handbrake lever and the rear parking brakes.

Symptoms Of Wear Or Failure:
Common symptoms of a worn or damaged handbrake cable include:

• Handbrake lever travelling unusually high
• Vehicle not holding securely when parked
• Handbrake requiring frequent adjustment
• One rear wheel holding more strongly than the other
• Parking brake dragging after release
• Handbrake lever feeling unusually stiff
• Cable movement feeling rough or notchy
• Rear brake sticking
• Grinding or scraping from the rear brake
• Excessive heat from one rear wheel
• Visible cable corrosion
• Split or damaged outer cable sheath
• Frayed inner cable
• Damaged rubber protection boots
• Cable seized inside its outer casing

A worn cable can sometimes still move but may no longer transfer the correct amount of force to the parking brake.

Why Replacement Matters:
A defective handbrake cable can compromise the vehicle's ability to remain stationary when parked.

This is particularly important when parking:

• On hills
• On uneven ground
• During servicing
• Where reliable mechanical restraint is required

Replacement restores the mechanical link between the handbrake lever and rear parking brakes.

A correctly operating cable helps provide:

• Reliable parking-brake engagement
• Proper release
• Balanced braking between rear wheels
• Predictable handbrake lever travel
• Reduced risk of brake drag
