Too much grease, my slack adjuster boot is now a balloon! Please help, new truck owner...

no problem. leave it like that. next time don't add grease to that fitting

 

You did good, you didnt blow them all out like I did when I first got my truck

 

ohh , no, no, no. take out the slack adjuster , take out excessive grease. that's a violation of BLA bla bla codes and big safety issue. If you will be stopped by dot, you will be analyzed*. Also that extra grease will cause brake system failure... what else can be said ? )))))

 

I was serious when I said leave it like that. after one hour of driving/breaking that extra grease will come out itself... no need to worry about this issue. If boot was busted I would say change the boot...

 

If it really bothers you that much to where you think it's an issue..........

Poke a hole it the boot and squeeze out the excess grease.

My 2 cents.......they are not long for the world anyhow. The Clevis pin joints look like there near frozen solid. Replacement might not be a terrible idea.

 

You can slide a straight pick between the boot and actuator rod to relieve the excess grease. I do this every time I grease Meritor ASA's.
