Handbrake Release Button Replacement

Finally figured out a solution of how to replace the chrome tip
I also want to caution everyone always be leery of any post that starts with "hey, watch this..." Luckily this didn't turn out that way.

What is helpful to know is you don't need to remove the console to do this. But I needed to do complete another DIY I'm doing with USB ports so it was already off.

Before I started this I planned to remove the handbrake plastic trim cover (tan) hoping it would expose some release catch but after 24 years that wasn't happening.



As you can see trying to remove the old button with my channel locks only resulted in shearing off the tip. That out of the way I approached this the same as you might if a bolt had snapped off and needed to be removed.





So I began with a 1/8" drill bit and drilled a series of holes around the button face.



I avoided drilling too close to the threaded metal shaft and possibly damaging any threads.



Eventually I drilled enough holes to weaken the button's remaining structure and grip.


Now it was a simple matter of backing it off counterclockwise using a pair of needle-nose pliers.


Once off be careful not to loose the spring.


This picture doesn't clearly show the shaft as threaded but it is.


Old broken button with spring.


New shiny button with spring.


Reinsert and hand thread back on.


I thought this was ironic it's the jar cap gripper given to me by the salesman who sold me my first new Honda... an 89SE-i. Its the most useful gadget I ever received and its held up well.


So of course it was perfect to tighten the new button without marring the finish.


Finally installed... somehow I don't recall the old button protruding this much. In my research someone mentioned the button may have a tapered thread so when its threaded by hand it might only screw down about 2/3. The problem is how to tighten more without using a tool and risk damaging the finish. Perhaps adding a small spray of silicon lubricant into the button prior to installing would work? For now its on well enough so I won't tempt fate.


After testing it multiple times it functions well.


As far as I know this DIY isn't replicated anywhere so it may prove useful if an admin will sticky it... hope you find it useful.

It will prove useful to me because I ordered a couple buttons myself. I was dreading having to take the lever apart to replace the button - now I know I don't have to!

You think maybe you clamped down too hard with the pliers when trying to remove it?

Just an FYI - if anyone is interested

During my research trying to find a DYI I discovered that "Science of Speed" here in Chandler, AZ does performance work and as well as sell performance products.

One of those products are their own "Science of Speed Billet E-Brake Buttons"

Did you know even the earliest 1st Gen NSX was saddled with the same lowly OEM Honda E-Brake buttons?

Anyway these are a bit pricey but what on the NSX isn't?
On the plus side at least they aren't plastic...

All are priced the same at $39.50

They offer 4 versions:
> polished chrome ceramic
> titanium gunmetal ceramic
> satin black ceramic
> satin silver clear anodized



So if your looking for something more custom than OEM you might want to check them out:
https://www.scienceofspeed.com/index...ke-button.html

Full disclosure:
I have not been compensated nor do I know anyone who works there but I do have a friend whose NSX was serviced there.

Good question, I'm really not sure. I know I didn't care about damaging it but didn't expect it to break either. It felt like it was unthreading when I did it but obviously that didn't happen.

If there is one thing Arizona climate is good at is accelerating the failure rates of rubber and plastics that's why car makers love it here... hot weather testing. My best guess is after 24 years and constant heat it partially fused the plastic threads to the mating metal shaft. Combined with the brittleness of the old plastic it just couldn't deal with the torque.

Raf99 is very helpful Raf99 is very helpful
I always wondered this! Thanks. I swapped my ebrake handle for a OEM black one but the button chrome is wore off. I have a spare I can use but couldn't figure out the button. & looks like I'll destroy it getting it off..... gone to try.
