John504,
Thanks for your reply.
That is a terrible experience, sorry to hear.
Do you know what years and models are all interchangeable?
I've had bad experiences with Napa.
Once with power steering hose. I had to press the pulley on and off several times.
Where would you recommend I get a booster.?
Thanks

the last booster to fail was from GM. I don't know what to recommend...... as stated my Vette specialty shop thinks ALL of the boosters are single source. they have seen failure on 3-4 c4's now and they don't know what to recommend either. you might want to try to find a metal body booster if available, no way it could be any worse.

I just ordered one from the local O'Reillys store.
It's metal cost $121 + $11, for expedited shipping.
Should get it Tuesday.
Thanks for your help.

Yes. Inner rubber liner comes off...acts like a one-way valve.

Thanks Ghostrider.
I installed the new brake hoses and the original master cylinder. Put the pads and caliper back on. Let fluid drip through the system till it came out the bleeders.
Nothing more to do till I get the booster.
I appreciate everyones help.

Well it's a bummer.
I put the booster on.
The brake pedal just flops around the top 3 inches.
Then it feels like it hit a rock.
The pedal never pumps up. I get about 2inches of travel that I can use to bleed the brakes.
Also now the brake light is on.
So I ordered a master cylinder & will install it tomorrow.

Might need to adjust the rod in the booster.

Thanks for trying to help, I can't adjust 3" of pedal movement with a 1/4 of adjustment on the intermediate rod.
To me, if a new master cylinder doesn't work, I'm going to sail the car off a bridge, 😂
If I pull it out of the river I guess I'll try wheel calipers.
$270 so far.

Thanks guys I'll get one tomorrow and try that.
FWIW. The replacement parts coming out of the auto parts box stores is full on crap these days.
Even NAPA which I've regarded as better than than most is still garbage.

If you can find rebuild kits and do it yourself.

Success! New master cylinder from O'reilly.
Fixed everything.
The old one from Napa never did work right.
Thank you everyone for all your input.

Good for you. You don't have to drive but once you get going, stopping isn't an option.

Yes sir, Everyone had plausible solutions.
I'm glad I have new hoses also.
I did waste $120 and a lot of work on that booster.
The thing is, when you recently replaced a part, master cylinder, you tend to believe that it can't be that part.
Live and learn, I'm just glad you guys got my back .
Thank you everyone.
