 Booster Delete Installation Instructions – ED/EF

12 in stock

The benefits of deleting your brake booster for performance driving are:

  • Reduced compliance between the pedal and the master cylinder, which translates to a firm pedal feel
  • No lag between the pedal force and the pressure in the brake lines thus improved braking control
  • Reduced sensitivity, which makes modulating brake force easier
  • Weight reduction due to removing booster

Unique features of the Honed booster delete kit:

  • 6:1 pedal ratio to reduce pedal effort commonly associated with manual brake conversion. This is achieved with an offset mounting location for the master cylinder and creating a new mounting hole in your brake pedal for the push rod clevis (template provided)
  • Designed to utilize OEM Honda master cylinders, which are a dual-cylinder design (safe) and are comparable quality to your original master cylinder
  • Mounts with studs, the same way as a standard Honda booster

In order to install this setup in your car you will need either a 7/8″ or 13/16″ master cylinder, depending on the size of your brake discs (see below). The size of your master cylinder will be written on the side.

OEM Master Cylinder Part Numbers

7/8″
RHD: 46100-S04-J53
LHD: 46100-S04-A14, 46100-S04-L53

13/16″
RHD: 46100-S04-J01
LHD: 46100-S04-A02

With 282mm factory front brakes or 282mm+ rotors with aftermarket calipers (Spoon, Willwood etc.) we recommend using the 7/8″ master cylinder.

With 262mm (or smaller) factory front brakes we recommend using the 13/16″ master cylinder.

We source master cylinders from a local pick-a-part wrecker where they can be had for a reasonable price, but you can also source them new from Honda.

It is perfectly fine to use our booster delete kit with the OEM proportioning valve.

If you are replacing the original booster and master cylinder from your EG and you intend to keep the OEM proportioning valve on the firewall you can reuse the factory hard lines from the OEM proportioning valve

If you are using an aftermarket proportioning valve, you may need to make new lines to suit the new master cylinder location.

We have a blog post on our site that guides you through the installation process:

    Perfect for brake modulation, high quality fit and finish. Easy to follow installation instructions.

  7. Ramon Ceja (verified owner)

    Precisely engineered part at a great price. The brake pedal feels nice and firm. It’s a lot easier to drive than I thought. Definitely worth every penny.

    A quality product, but I bought based on the install instructions which are wrong for my USDM 90 Civic Hatch. Dropping the brake pedal for a correct install requires dropping complete pedal box along with steering column and several other parts. Turns a 20 minute job into a much more complicated procedure. It is not just one 14mm bolt to drop the brake pedal like described in the install instructions.

    Super easy to install. You can take out the whole assy, or just take out the pedal itself. In the process of waiting for wheels so I can go drive it.
