You can adjust the drums with a tool that slips into the slot on the inner side of the drum. But they'll just go right back to where they were since they are auto adjusting. What you really want is to get a line lock setup for your car if you really intend to do power brakes all the time.

The drums will self adjust when you drive in reverse & apply the brakes, otherwise this is a good trick for the track.

Hell no it's not. think about it, at the end of the 1/4 mile, what do you do? You brake...at high speeds...quickly. How is having no pressure applied to the rear a "good" tip for the track?

you have 70-80% braking force on the front discs. thats why rear shoes last so much longer than front discs.

new graemlems again

Rear drum shoes are what, $14? Why care about wearing them out? This reminds me of "if I race my car, will I break the engine?" I'm not trying to be harsh, but think about it- Anything we do out of normal driving is hard on the drivetrain; when your rear shoes get worn down, replace 'em! There's a picture-by-picture procedure in the Haynes 82-92 Camaro (or 82-92 Firebird) book.

an "off highway"alternative would be to just removes the rear shoes.

very "off highway"

Actually, is that possible? Wouldn't you have to remove all the springs and everything, too? Also, wouldn't the wheel cylinder's piston shoot out the side? I don't think there's any provision to keep the wheel cylinder's piston inside the wheel cylinder; the thing might overextend itself.

Hey, wait... couldn't you use a hose crimper on the rear axle-to-body hose instead? You know those things; they look like little vise-grips, and crimp hoses shut (like fuel lines).

I still think it's a bad idea.

Its true 70 to 80 percent of your braking is from the front brakes .
However,your brakes are designed so that the rear brakes take up first, before the front brakes. Adjusting to zero drag will cause you to lose alot of your pedal. Bad Idea.
A line lock makes more sense to me if power braking is what you want.

I'd love to get a line lock.. that'd be bitchin' at the track...

1. MSD 6AL box
2. 2-stage RPM limiter
3. Linelock

Pull up to the line, engage the first limiter, engage the linelock, and mash the go-pedal to the floor. When the light goes green, hit a pushbutton mounted to a spiral cord- your 2nd limiter (redline) kicks in, linelock shuts off, and you've got one HELL of a reaction time!

Problem is; how safe is a linelock for the street? How do they react to heat & weather & other situations that street cars see that race cars don't?

Actually guys, there is actually a Technical Safety Bulletin (TSB) on the automatic camaros and a recall on the manual camaros about the rear brakes. If I remember correctly it has something to do with the self adjuster malfunctioning. It's actually an emergency brake tsb/recall, but it is because the rear brakes malfunction, and that's what the e-brake uses to hold the car. GM admits there is problem, but won't foot the bill for the auto, only the manual because it is needed more. Nice, huh?

BTW, You can't just take off the rear pads, because you're braking system isan entire system, not front/bak seperate, when you lose fluid from the rear, it will affect the front, no matter what that little regulator is supposed to do. Pinching off the line is the only real way to remove the rear brakes. I agree wit Ovrclck350 though, not a good idea.

any ideas on where to get a line lock?
possibly without having to go online?
if its in Jegs SUmmit or JC whitney lemme know ok?

and is the line lock expensive at all?
and if i ever get one could a average guy like me install it in the car?:lala: :lala: :lala: :lala: :lala: :lala: :lala: :lala:

They're like $30, easy to install, and a lot safer than "zero drag drums"

grimesjim1, I've only heard of that recall/TSB info for f-bodies with rear discs only, not rear drums. In fact, look for my message about a "hard pedal"- I put the recall kit into my calipers. Search for messages by me on the Suspension/Drivetrain board; I got the recall kit for under $50 from http://www.gmpartsdirect.com . Individually, the TSB parts were well over $200! (The recall kit # is the one GM doesn't want us to know.)

Is that why my E Brake arm pulls up so high?
I've got an '85
Line locks.
Work real good for an antitheft item, too!!
All you are really doing it adding a solenoid into the brake system.
Look at your brake system at the firewall.
That's where you add it.
Do you want to mess with that?
Can you mess with that?
Got the proper tools?
Look at www.MrGasket.com for the Hurst Line Lock.

Recalls and TSB's

If you want to get a list of recall and TSB's here is a site you that has them. The list is free, but if you want the reacall notice or TSB they want $24.95 year for online access.

If you were to give a dealership the document number would they be able to give you the particular recall notice or TSB?
