I'm in the process of replacing the power brake booster. Does anyone have a trick to getting the nuts off that hold it to the studs on the firewall? I have the top one closest to the fender off but getting the other 3 is proving difficult. Any help would be very welcome.

 

Buy a flat ratchet wrench.

 

Thanks for the tip Nomad, I'll be stopping at Sears on the way home from work!

 

I couldn't get my racheting box end wrench in there. Just had to break them loose with an open end, and then get my fingers in there to turn them. Make sure you hold it against the firewall while turning the nuts and it will come off easier than having the weight hanging on the nuts.

 

Thanks for the tip Nomad, I picked up a set of the ratchet wrenches with the twist(they're longer). I was able to get on the lower nut easily and loosened it enough to get a shorter ratchet wrench on. It took a while but the hardest one is off. Hopefully have it swapped out tomorrow. Thanks again for the help.

 

Its cool. I've been there before.

 

All done finally. It'd have been about impossible without the ratchet wrench. Tomorrow I install the new master cylinder. Thanks again for the tip Nomad.

 

I have the same problem and even with the ratchet spanner i cant get it turned

 

Sometimes you just have to use an open end and 1/4 turn at a time. Once they're loose, they usually can spin off by hand if you support the booster to keep weight off the nuts.

 

Do you have a flat wrench or a reversible with a bend in it? You need a flat one.
