I have a 1991 Camaro RS 305 4 Speed Automatic that I just got. I've changed the oil,changed fuel filter,and flushed power steering fluid. I still need to flush the brakes and coolant. Then change transmission fluid,so you'll see a lot of me here. My latest problem is cracking open the rear drum brake bleeder valves. They sit in a recessed hole that makes it impossible to get a wrench on them. What I wanted to do is put a little hose over the valve and flush them into a soda bottle,but all I can think of at this point is using a socket,but if I do that I won't be able to use a hose on the valve. Is the what I'll have to do,or do some of you experienced guys know a better way?

 

What about a box wrench with a deep offset?

 

make sure it's loosened with the socket.

Buy a specific bleeder wrench, a deep offset wrench, or modify a socket to allow for hose attachment.

 

These Drums are a real pain to bleed, so, I bought speed bleeders and installed em.. Easy Peasy Now..

 

Suck the fluid out of the master cyl first and pour fresh fluid in. Are the wheel cyls original? If so I'd buy new and then bleed. Wheel cyls are cheap and they rust inside as brake fluid attracts moisture and wheel cyls are iron.
Use a socket, open the bleeders and let them gravity bleed and keep the MC full. Aside from a socket you can buy a special bleeder wrench.

 

use a good snug fitting 6 point socket to crack them loose, then let gravity do the hard work of bleeding the brakes for you... just let it run until you see clear fluid, then stick the socket back on and tighten it up..
