Finally got around to bleeding the Wilwood Dynalite calipers from the Trackspeed engineering kit, but I can't seem to get the pedal firm to my liking. Obviously I've only used the top 2 bleeders on each caliper.

I've bled a few cars before and the result has always been a good firm pedal without any issues.

There's no apparant leaks anywhere. All fittings are tight and clean. I redid the rear brakes and this only helped so much.

Is there this big a difference in piston surface that my pedal will not feel as firm as with the oem single pot calipers?

The car will stop, but I just don't have any confidence in them.

Tell me where I messed up.

First one to give me the solution will be rewarded with kittie pictures.

In this sittuation I started over, from the top down. Bench bleed the master and work your way down. I also hit all 4 bleeders on each caliper because these wilwoods are a major pain in the *** in general and I know one will ****-up sooner than later.

In my experience it always helps to tap on the caliper with a dead blow hammer to free all the air bubbles that get stuck inside. You will be surprised how many tiny bubbles come out after you do it. But if you're not getting a good pedal at all you probably have more problems, like air in the master cylinder.

If you have a spare brake reservoir cap, drill a hole in it, push a hose in a bit, then put your air pistol in. Set the compressor down to about 5-10 psi and crack the bleeders one at a time, starting with the brake furthest from the master cylinder. It took about a two quarts of 5.1 fluid before I was happy with the pedal pressure. Before unscrewing the cap, put a towel around it. It sometimes squirts a bit of fluid as its releasing pressure.

Hopefully all this made sense.

*edit* or just buy speed bleeders. They make bleeding the brakes a breeze.

how bout your master brake cylinder???? maybe the rubber piston inside leaking?

+1 There's a reason they are there.

The reason they are there is so that the caliper can be used on either the left or right side. I actually removed the bottom ones and replaced the top ones with speedbleeders.
