Line Lock as an emergency brake? (Page 1/2)
str8maxn DEC 16, 02:36 PM
Soon I'll be adding rear Corvette brakes. The existing Fiero brake cables may or may not be useable. ( I still on the fence on C4 or C6 rear calipers. )

I was thinking of using an universal electric brake but this is a $300-$500 kit. I then came across a line lock kit used for burn outs at only $35-$60 .

Could one use a line lock kit as an emergency brake?

As a parking brake, maybe.

As an Emergency brake to stop the car due to a hydraulic failure - NO!

Parking brake only....

This has been suggested numerous times here over the years. I seem to recall that using Line Lock as a parking brake was impractical. Perhaps it was due to it requiring an electrical draw the whole time it was being implemented... which isn't such a good idea when a car is not running.

In theory the Fiero doesn't really need an emergency brake due to the dual master cylinder that backs up front and rear brake systems. An emergency brake would only be necessary only for total master cylinder failure and then a line lock may or may not even work.

My main purpose would be to have the car on and idling. I have slopped drive way and find myself using a rubber stopper to stop the car while its on; warming the car up and\or working out issues.


Once parked leaving it in first gear is good enough for me.

No And Cannot use as Parking Brake either.

Doesn't matter mechanical or electric control.
They are for Temporally Use Only w/ driver in the vehicle.

W/ lock on the system will leak down, often sooner not later, and let car to move at a whim.
Because Brake Hydraulic System is not make to take pressure ~ 10 - 30 minutes let alone Hours.

If left parked w/ line lock on and hits someone or something expect to get sued and car insurance not playing.

And Most places is Illegal as E-brake and P-brake whether or not have State Inspections.

The line-lock brake I'm familiar with for heavy vehicles do not require electric. You push the brake pedal hard as you can and turn a lever to lock the fluid pressure in the line. They also have been known to dissipate the pressure in the middle of the night and allow the vehicle to quietly creep away. Many now are labeled with warning to not use in place of the original equipment. Google Mico Brake.

If you have vehicle inspections where you live, the line lock will not legally be considered a parking brake. So your car would not pass the inspection.
