Default Replaced Brake Booster 2x For Cracks

I'm getting pretty good at changing power brake boosters.
I changed my original back in 07, because of a bad diaphragm.
The replacement lasted until this spring, when I found a crack in it, after doing a cam change. It made no noise, pedal was hard, engine ran terrible.
I covered the crack with duct tape and took it for a spin. Ran great!
So, I went to Advance Auto, where I bought the booster and got another, for free, thanks to the lifetime warranty.

It lasted 5 weeks, when it cracked, too. (In a different place.)

Thank God for warranties.

Got another free one and I'm back in business.......... again.

Moral of the story: If you have a hard brake pedal, feel all around for cracks. And most of all, buy one that comes with a lifetime warranty.

An interesting side note: both of my replacement boosters front covers have a date tag from 1996 and the back covers have a date of 2001. Maybe they're reusing the original front covers and using new rears when they rebuild them?

1st, cracked by exhaust manifold.



2nd, cracked above vacuum fitting.

the metal ones that exchange with the plastic sometimes hold up better

I got the same one from Advance. It works fine, but it actualy moves to the right a little when I step on the brake. (my friend was watching it as we were bleeding the brakes). With my arthritis its a real PITA to get under the dash on my `90. Hope it lasts.

PS: the nuts are tight, I checked.

More important that a spare tire.

the mounting surface on your firewall is cracked, you may want to fix it prior to shoving your foot thru it, its entertaining but not fun
