OE Match
Front caliper mounting bracket locking plate by OE Match, this laser-cut component has a zinc-plated finish.
Fits
- Porsche 911 - 1965 to 1968 (Short wheel base)
- Porsche 912 - 1965 to 1968 (Short wheel base)
Check fitment for your specific vehicle (model, year, engine) before ordering.

What This Product Does
This plate provides the locking element at the front brake caliper mounting bracket. It is mounting hardware, rather than a complete caliper, carrier or brake disc shield.
Functions
- Provides locking retention at the caliper mounting.
- Replaces the corresponding plate during repair or restoration.
Technical Details
- Position: Front.
- Manufacturing method: laser cutting.
- Surface treatment: zinc plating.
- Sold individually - 4 needed per car
- Existing product reference: 1665000100.
- Assembly diagram identifies tab washer 90135148111 at item 8, quantity 4; associated retaining bracket 90135108512 appears separately at item 6, quantity 2, for 911 /TU 912.
Why Replacement Matters
During brake repairs or restoration, inspect the locking plates and adjoining mounting hardware before reassembly. Replacement should address the condition of the locking component itself; changing this plate does not remedy hydraulic leaks, sticking caliper pistons or worn friction components.
FAQs
How many plates are required?
The supplied information specifies four per vehicle, with each plate sold separately.
Is this a complete mounting bracket?
No. The product is the locking plate; the retaining bracket is identified as a separate component in the assembly diagram.
Does the application cover later 911 models?
The stated fitment is limited to the listed 1965–1968 short-wheelbase 911 and 912 applications.

Front Brake Calipers
Restore confident braking performance with Front Brake
Calipers, designed for Porsche 911 3.2 Carrera
models from 1984 to 1989. Positioned at the front axle, these calipers are
essential braking components responsible for applying clamping force to the
brake discs, helping slow the vehicle safely and consistently.
Fits:
- Porsche 911 1984-1986 3.2L
- Porsche 911 1987-1989 3.2L G50
Brake calipers work together with the brake pads, discs and hydraulic braking system. When the brake pedal is pressed, brake fluid pressure forces the caliper pistons to push the pads against the disc, creating friction and reducing vehicle speed. Because the front brakes handle a large proportion of braking force, properly functioning front calipers are critical for safe road use and predictable braking performance.
Over time, calipers can suffer from corrosion, seized pistons, worn seals, fluid leaks and uneven pad movement. Replacing worn or faulty front calipers helps restore braking balance, pedal feel and stopping confidence.
What Do Front Brake Calipers Do?
Front brake calipers convert hydraulic pressure from the braking system into mechanical clamping force. This force presses the brake pads against the rotating brake discs, generating the friction needed to slow or stop the vehicle.
Correctly functioning front calipers help provide:
Strong and consistent braking force Stable pedal feel Balanced front braking performance Even brake pad wear Reliable stopping power Improved safety in everyday and spirited drivingSymptoms of Brake Caliper Wear or Failure
Brake calipers operate in a harsh environment and are exposed to heat, road debris, moisture and brake dust. Over time, internal seals, pistons and sliding surfaces can deteriorate.
Common symptoms of worn or failing front brake calipers include:
Vehicle pulling to one side under braking Uneven brake pad wear Brake fluid leaks around the caliper Spongy or inconsistent brake pedal feel Reduced braking performance Brake drag or sticking brakes Excessive brake dust on one wheel Burning smell after driving Overheating brake disc or wheel Squealing, grinding or rubbing noises Brake warning light caused by fluid lossIf a caliper piston sticks or a seal fails, braking performance can become unpredictable and unsafe.
Why Brake Caliper Replacement Matters
Replacing worn or faulty front brake calipers is essential for restoring safe and predictable braking performance. A failing caliper can cause brake imbalance, overheating, premature pad and disc wear and reduced stopping power.
Replacement helps:
Restore correct braking force Improve pedal feel and response Prevent brake drag and overheating Reduce uneven pad and disc wear Eliminate hydraulic fluid leaks Maintain balanced braking performance Improve safety and driver confidenceFor a classic Porsche 911 3.2 Carrera, maintaining the braking system in excellent condition is vital for preserving the driving experience and safety the car was engineered to deliver.
Features & Benefits
- Restores reliable braking performance
- Supports strong and consistent stopping power
- Helps maintain correct brake pedal feel
- Ideal for maintenance, repair and restoration projects
- Direct replacement for worn or damaged original calipers
Keep your Porsche 911 3.2 Carrera braking system performing safely and consistently with front brake calipers from Design911

These are direct replacement calipers for the rear left (part number 91135242500) or rear right (part number 91135242600) side of a mid-1980s Porsche 911. They are manufactured to the dimensions, fitment, and technical specifications of the original. Replacing these calipers restores the correct brake pressure, pad alignment, and brake disc-to-rear wheel contact, restoring braking balance and safety.
Porsche 911 1984 - 1989
Brake calipers are crucial for safe, controlled stopping. Over time, calipers can suffer from corrosion, seized or sticking pistons, worn seals, fluid leakage or uneven pad wear. Especially on aging cars, the rear calipers may lose proper clamping force, causing longer stopping distances, uneven braking, noise or poor pad life.
Replace these calipers when you notice:
• Brake fluid leakage around the caliper body or piston area
• Uneven or rapid pad wear on the rear wheel
• Reduced braking performance, dragging wheel or vibration
• Maintenance/restore of the braking system during a rebuild
Installing a correct-fit caliper restores proper braking clamp, pad and rotor alignment and ensures your classic Porsche retains its intended braking performance and safety.
