BBK question

Wes Howell · 03-24-2011, 12:28 AM

How does a BBK - like the Stoptech trophy kit, for example, affect the e-brake? Does the e-brake still work? need extra parts? does it keep OEM parts, etc?

Thanks

(guess it's kind of a lousy time to ask since I bought my BBK, but I just didn't think of it)

Thanks!

Short answer, no. You don't need to do anything with e-brake.
However, some race design brakes do require removing the ebrake, but they would be written in discription.

Yes, your e-brake will still work. There is no extra parts to install during the BBk installation process and oem e-brake components are retained with the exception of the oem e-brake drum, which is part of the rear rotor, but it's replaced by the trophy's.

Like what Harold said. The rear rotors have a steel rear drum for the e-brake, and weight a ton compared to the fronts.

The oem is a steel drum. However, the Trophy Sport and most BBK's use a aluminum drum/hat.

It depends on who makes the kit, and whether they intend it to be usable for handbrake turns or not. The aluminum e-brake drum won't stand up to that kind of punishment, where a cast iron drum will.

Thank you.

That's what I thought. Maybe it's just the Trophy system?

Here's a picture of my rear axle w/o the OEM disc/drum. You can see the e brake shoes behind the hub.

And I believe that the OEM drum is aluminium... correct me if I am wrong.

^ the OEM front brakes have an aluminum hat, but the rears are steel

rzm3 · 03-24-2011, 10:18 PM

Look the same to me... L: rear, R: front

False.

Both hats are Al.

The Oem rotors rear hats are aluminium, but have a steel liner pressed in.

Brembo and Stoptech use aluminium hats that are hard anodised.

Alcon uses a steel rear hat which weighs a ton

E-Brake functions just the same. Just don't drive with the E-brake on.

Get Stop Tech Trophy, you will love it.

You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
