Aim:
In the event of requiring a dodgy brake booster, you have options of getting the original one reconditioned or replacing it with a new or a pre-loved one. A dodgy booster may be characterised by a hissing noise suggesting the rubber seal is damaged. You may even experience a loss of braking power. This article is based on a EG8 civic sedan.

Steps:

This black UFO is no longer Unidentified...it's the brake booster with the brake master cylinder removed from it (removal is via undoing the 2 screws either side of the central piston and pulling away.

On the inside of the firewall are four bolts of the booster that are protruding. Remove the nuts A&B (2 more are on the other side of steering column). Use screwdriver C to push away clip D so you can hammer out the pin which holds the booster to the brake pedal E

Pull the booster off the firewall. As you can see stupid shock tower B is preventing removal so I had to use spanners to remove the connecter A which holds the pin that I previously hammered out. I also had to loosen the clutch cylinder C to allow sideways movement and eventual removal of the booster.

The replacement part is the reverse of this process. So give it a go yourself. I am not a mechanic so don't sue me...follow these instructions at your own risk.

im just wondering serious question.

I understand there is brake booster delete kits available out there.
But its still has resivour in the engine bay itself.

In search of a clean shaved bay.
Happy to go with custom fabricators if need be.

Underdash booster/reservoirs aren't anything new. You can buy off the shelf kits but they are all designed for older cars. Mustang's/falcons etc.

What kind of car is that in?

Edit: crx? More info required

But then again thats another object in the engine bay.
Which i was hoping can be completely removed.

well if you delete the booster and still want to keep a decent pedal feel, its good to upgrade to a bigger diam M/C

Hmm fair call. Well in that guys thread he talks about the time needed to Fab it up, get it right etc. To pay some one you'd be looking at a few thousand bucks. Plus he said it doesn't fit under the standard dash.
