Bleeding 4 piston calipers

[mustbereel]

I have Wilwood 4 piston calipers on my Heidts IRS and am at the point where I need to bleed them. They have 4 bleeder valves, two on top and two on the bottom. Do I have to bleed each valve? Since the valves have to be facing up when bleeding I will have to remove the calipers and flip them over to bleed the lower valves. I really don't want to pull them back out but I will not take shortcuts when it comes to brakes.

I have searched Wilwood's site, searched Stangnet and done a general web search but I can't find any info specific to 4 piston calipers. Does anyone know the procedure?

Thanks,
Brad

use the top bleeder screws. they put bleeder screws on the bottom so the piston can be mounted in any position, kind of a universal fit caliper. all the air is going to rise to the top of the caliper so you need to use the top bleeder screws.

That's what I was hoping for. Thanks for the info.
