Will an early GLC brake booster fit on an RX3?
 

Has anyone tried using an early GLC (like a '78) brake vacuum booster on an RX3?

It should, but they don't work very well...even on GLC's. My brakes have always been a little scary. FB booster might be a better option.

Thanks for the confirmation. My booster finally gave up the ghost. I'm just looking for a drop in fix. The GLC part is available at parts stores, but the RX3 part needs to be sent in and rebuilt.

I have one that was rebuilt a few years back. Been sitting on the shelf as upgraded all of my RX-3s to FB. Come over and inspect it. Lmk

Thanks, I will PM you.
I'll probably want to upgrade to a larger booster too, but it will have to be later.
