What Wilwood calipers do I have and what size are bleeders?

[Mark1567]

I have some new Wilwood 4 piston calip[ers on the rear of my 5/1600, and I got them from KarTeka couple years ago. I'll see if I have a picture of them. Hell I dont have a p[icture and the car is not with me now but I am wanting to order speed bleeders for all four wheels and the turning braks but I don't know the correct thread size and pitch. Anybody happen to know what the sizes might be and if they use the same on alot of their calipers. I can go pull one tomorrow and measure otto be certain I order the correct speed bleeders.

The majority of wilwood race calipers use the same bleeder size.

thats what I figured buy what size would that be?I was going to order speed bleeders tonight but better nake sure I have right size. I will probably have to go down to the shop and take one off and measure to be sure.

All the info is on wilwoods website.

Wilwood says they do not recommend using Speed Bleeders with their calipers. Wonder what the reason might be? I have only used them on one of my cars and so far have not noticed any problems from using speed bleeders.

The manufacturer is not known for high quality parts and or good quality control. If the speed bleeders fail you will loose your brakes.

I can see where that could happen, if the check ball of valve does not seal properly and under high pressure could leak. I have the suction device that uses the air compressor but for some reason, I can't seem to get a good clean flow without bubbles. It might be when backing out the bleeder, it seems like it is sucking air from around the threads. Maybe I should take the bleeders out and apply some thread sealant. I get good bleeds when doing it manaully with a helper though but I don't always have someone to help.

I just put a length of clear tube on the bleeder and suspend it vertically. Open the bleeder and use the pedal to pump fluid thru the system. You can see the air bubbles in the clear tube and you can clearly see when they stop. When I've got a solid column of fluid with no bubbles, I just close the bleeder, pinch off the tube, pull it off the bleeder and then dump the captured fluid back into the reservoir.
