Hydra Boost Return Spring?
I was going through some parts diagrams and saw the hydro boost brake pedal has some sort of return spring(#14). My hydro boost setup dose not have this spring. As I either lost it during disassembly or it was not there to begin with.
So dose anyone have one they could measure for me, so I can find a suitable replacement? Thanks

My 87 has one. It hooks around the top of the pedal though, not to the tab like in your picture. I picked one up through LMC.

Re: Hydra Boost Return Spring?
I pulled my hydroboost and pedal assembly from a '82-ish truck. The spring and the attachment tab look identical to your diagram.

Re: Hydra Boost Return Spring?
Are you only missing the spring?

Yes, the tab is still hanging there.
