Official: Brake Pad Knock Back Thread

Todd-
any updates? I had heard that Wilwood now includes the improved bracket...

Gonzo-
Have those steel brackets proven to work or cure the issue, and do you sell them? How about thos pedals you made for the Wilwood base as well?

Kinda, I got the tapered bearing axles a few weeks ago but they were machined wrong. I took some measurments and sent them back to moser. They paid for shipping each way and the repair. I just got them back last Friday and proceeded to put them in but noticed one of the wheel studs got boogered up in there lathe and now I'm waiting on a stud. I'll be racing Sunday and that will be the true test. There is definitley no end play now in either side. I'll update you guys one I drive and race Sunday.

How did the weekend go? I am waiting with baited breath and a poised pen and checkbook.

It was better but still not fixed. For normal street driving it's fine and an improvement of a roller bearing. Once race time comes around I lose about 2-3 inches of pedal after a couple turns. It's more managable but not what I hoped for when I bought the brakes. If you are getting ready to buy and rear end, make sure it's a tapered setup or even a full floater if you plan to race a bunch. If I knew then what I know now......

Sounds like a brake pad issue.. If you are not having problems on the street but then comes race time and you are losing some pedal.. What is the part # on the pad you have right now? You need to find pads that have a higher coefficient of friction when you get them hot when autocrossing or open tracking.. More than likely you have a BP10 or 20 which will fade after a couple of laps.. street pads..

What brake fluid are you running? I hope you are not running dot 5 silcone..

I have a car in the shop that is set up for open tracking with smaller rotors, calipers & tapper bearings & have never had the customer complain about losing pedal or pad knock back

Hey Gonzo,
I read your PM and was going to look into the pads before I replied. I'm pretty sure they are BP10's. I looked recently and checked them on Wilwoods site. They are street mild track pads. It's not the pads even though braking improves with heat. I can replicate it easily on the street by doing a slalom. The pedal engagment point drops 2-3 inches. I'm running Wilwood Dot 3 fluid.

I would try some 15E or 15B pads.. I would not run BP10s for agressive street driving or autocrossing.. I have tested all of Wilwood pads & these are the ones that have worked the best for me!

Don't rule out pads!

The new bracket from Wilwood helps but will not cure the problem.. If Vegas 69 gives me all the components that he has for the brake system I might be able to help.. If he was closer we would get this problem solved.. Maybe he will want to take a 5 hour drive!?!??

I have been thing of making these brackets for production..hmmmm

The machined pedals for the Wilwood base will see in the next couple of months in production.. tooling for the forgings will be ordered next week.. You didnt hear that from me though

Gonzo-
Let me know if you need another test vehicle, as my Camaro will have the Wilwood W4As on the rear with a 14" rotor. I'd say if there is any runout left, we'll be able to find it (but I hope not).

As for the pedals- that's some nice stuff. They'd be perfect anodized black. Like I said before, let me know if you need me to do some beta testing, cuz I have the same base going on my ride.

Todd- Good luck this weekend

[Cris@JCG]

I will let you know if I make another set of caliper brackets out of steel.. nice rear brake set up!

The pedals will be coming soon for the Wilwood bases.. from what I have heard the pads will be stainless & offered with different coatings on the pedals
