Title: Brake Booster Eccentric Bolt and Matching Hole
Post by: rbouch8828 on September 01, 2017, 23:48:39

On my original Brake Booster, there is an elongated hole on one side of the attach point where the brake side connects, that accepts an eccentric bolt. My replacement booster does not have this special cutout, just normal bolt holes.

Does anyone know what the function of the eccentric bolt was and whether I will have a problem using a common bolt and my new booster?

Thanks,
Roland

Hi,

It's for adjusting the height of the brakepedal.
No problem using a regular bolt except you will not be able to adjust the brakepedal.
Usually only an issue if you have a stick shift.
Expanding the hole to accept the eccentric bolt can also be done of course.

Hi Roland,
I undertook this exercise last year, here's my post with pics:

I enlarged the hole to accept the eccentric bolt.
Hope this helps.

Best,
Mike

Thanks for that. Didn't know what it was for and glad to know about how you made the changes.

Thank you both!
Roland

Not sure why brakes would be any different on a standard or an auto. Wouldn't both cars need to stop? :)

I have bought a drill bit and will try to enlarge the hole as you suggested.

Many thanks!

I used one of these drill bits when I enlarged the hole and used a slower speed on the drill.
It requires a little patience., the metal on the fork is quite tough.

I had no clue the eccentric bolt could be used to adjust braking power, happy I learned something new today.    ;)

My understanding is that on a manual car, being able to adjust the brakepedal relative to the clutchpedal position might be slightly more relevant than on an automatic gear car.
