Product Details

This is one of the best brake upgrades you can do to your M715 / M725! The stock brakes leaves a lot to be desired, especially if you have upgraded the drivetrain or added larger wheels and tires. This Hydroboost System uses power steering fluid to energize your system. These kits come stock on New Heavy Duty and Diesel Trucks for their amazing stopping power!

This unit will bolt straight to bolt holes on your firewall. This hydroboost unit will ship with the firewall mounting bolts and the nuts for the MC bolts. The accumulator may be a different color (shown in gold).

This hydroboost is a short-input style that requires a dimple-input master cylinder.  Long-input master cylinders are not compatible.

**Note: if you are converting from manual brakes, the manual brake pedal may sit higher with the hydroboost.  
**Note: If you order the pressure hoses, note that you may have to slightly bend the lines to fit correctly.  
Once ordered, contact us with your order number and we will email instructions / guides to help with the install.

**NOTE: DO NOT, under ANY circumstances, depress the brake pedal without the master cylinder fully connected / installed / seated!  If you do, this will cause the pushrod, spring, baffle and retainer to shoot out under incredible force and at incredible distances.  This has the potential to seriously injure bystanders and cause major damage.  It can also damage / ruin the hydroboost.
