Replaced brake booster, A few?
Replaced brake booster yesterday, stock 93 coupe. I was able to do it without having to remove master cylinder. Just had to move ASR out of the way.
My booster was cracked around the check valve, on the top edge of the outer body and was cracking from the check valve towards the center of the face where the master cylinder mounts.
I noticed when I bought the car that it was missing the 2 rubber caps on the check valve so I replaced them when I bought the car. When I removed the old booster I noticed that one of the rubber caps was cracking and the other was developing a hole in it.
Is there such a thing as too much vacuum and has anyone had any issues with the caps on the check valve? I used a reman Napa booster and the hardest part of doing the swap was the 2 inside bolts and getting the arm of the booster to go on the brake pedal. I used a drill and reamed out the hole on the plunger arm and it went on a lot easier.
Thanks to littlesk8cracker (spelling?) write up with photos when he did his booster.

Took old booster back to Napa to get core charge refunded and they wouldn't take it back. They said it couldn't be rebuilt because it was cracked so they couldn't take it. I told them that they were plastic and most failures I've heard of we're because of a cracked housing.
Has anyone ever returned a cracked brake booster and got their core charge refunded?

I returned a cracked plastic one as a core with no problems. I think it was at Advanced Auto, but can't remember. To be honest, most of those places don't even look at them though -- they just check to make sure it's the same type of part. I probably could have given them a booster off of a '85 Civic and they would have taken it

Don't know what your core charge is, but I have a good core for $30 shipped.
Or, Send me $25 and set it up so that my local NAPA store takes my core on your behalf.

I just replaced my brake booster (photos in another thread), and it is cracked as well. Now whether or not I get my core charge back is up to the people who sold it to me, but the box says I only get $20 of my $50 core if it's cracked. Since the booster was only $120, and I expected $200 I'm not going to gripe about the extra $30 if it comes up.
