Lyndon,

The only con is that it is slow. On some cars you can do it without removing the wheels but it is usually easier to just remove one wheel at a time if you don't want to get the whole car off the ground.

Also consider that for every minute the m/c or a valve is open glycol fluid is absorbing moisture.

I try to do brake flushes during very low humidity weather, which out in in So Cal typically occurs in the fall.

Re: gravity bleed

I can see doing the front brakes, but I dont know how you could do the back with out taking off the wheels?

Re: gravity bleed

You can't - the rear wheels have to come off. A home pressure bleeder takes 99% of the grief out of bleeding Corvette disc brakes.

John,
Is this the type that pressurizes the system from the master cylinder rather than creates a vacumn from each of the calipers? I have the vacumn type which seems to work OK, this however seems like it would be much faster.

Re: gravity bleed

Yup, pressurizes the master cylinder and you don't have to keep checking the fluid level in the master as you move from bleeder to bleeder - it keeps it full as you work.
