Dial In Your Pedal Feel Without Cutting a New Firewall Hole
Swapping in a hydraulic clutch or upgrading your brake master cylinder setup usually means fighting with pedal geometry that never quite feels right. This Swing Mount Tandem Master Cylinder Brake Pedal from Wilwood solves that by offering a 6.25:1 to 7.00:1 adjustable ratio in one forged aluminum assembly, so you can tune pedal feel to match your master cylinder bore and brake setup instead of settling for a fixed ratio that was never designed for your build.
Key Features
- Adjustable pedal ratio from 6.25:1 to 7.00:1 for dialing in pedal feel
- Forward swing mount design keeps master cylinders outside the firewall
- High strength reinforced forged aluminum pedal arm construction
- Bright finish stainless steel waffle style non-slip foot pad
- Black E-coated base and lever for corrosion resistance
- Mounts common tandem brake master cylinders with standard bolt spacing
- Includes hardware needed for most master cylinder mounting applications

Frequently Asked Questions
What is the Wilwood 340-17699?The 340-17699 is a swing mount tandem master cylinder brake pedal assembly from Wilwood with an adjustable 6.25:1 to 7.00:1 ratio, built from forged aluminum with a stainless steel waffle foot pad.
Will this pedal work with my stock master cylinder?It is designed to mount common tandem brake master cylinders with standard bolt spacing, but you should confirm your specific master cylinder's mounting flange dimensions before ordering since this pedal is intended for custom and race applications rather than a direct OEM replacement.
Can I use this with a hydraulic clutch setup too?This is a single brake pedal assembly. Wilwood offers a companion clutch pedal in the same swing mount family if you need matching hydraulic clutch actuation.
How do I change the pedal ratio?The pedal head adjusts vertically between multiple mounting positions, allowing you to select between the 6.25:1 and 7.00:1 ratios depending on the pedal feel and mounting clearance you need.
Does this pedal come with a master cylinder included?No, the master cylinder is sold separately. This assembly is the pedal and mounting hardware only.
What kind of vehicles is this pedal designed for?This is a universal application pedal intended for custom hot rods, race cars, and other purpose built vehicles where you are fabricating or modifying the pedal box area rather than replacing a factory pedal.
Do I need any special tools to install this?Basic hand tools are sufficient for mounting the pedal assembly. Wilwood recommends using blue threadlocker on the mounting screws and torquing to spec during installation.
Is there a warranty on this pedal assembly?Wilwood stands behind its pedal assemblies against manufacturing defects. Contact us with your order information if you experience a quality issue.
Can I return this if it does not work for my build?Yes, unused parts in original condition can be returned within our standard return window. Reach out to our support team to get the process started.
