I installed hurst line lock control onto my camaro. the line lock works as should but now my dash brake light wont shut off. wheels free spin like they should with no hangups. is it hooked up properly? im going to drop top brake line down lower also.

 

Does it stay on all the time in general or just when using the line lock? After releasing the line lock, does a quick stiff shove of the pedal shut it off? IIRC there are only two switches that can illuminate the Brake light. Parking brake and the switch in the proportioning valve. The valve shifts based off pressure differential between circuits.

I would speculate that when you hold the pedal down, actuate the lock, then let off the pedal allowing the MC bore to return, it is sucking the slider to the front channel to fill the void of the fluid not returning. Just out of curiosity, I have never had one of these on one of my cars, does the pedal return to the top of travel while the lock is actuated or does it sit slightly down?

 

the light didn't come on till I activated the line loc. pedal returns to normal position. wheels come unlocked and roll normal. the light stays on constantly and doesn't shut off

 

Try giving the brake pedal a quick hard stab after releasing. I have had mine shift during bleeding or when a caliper seal went. It took a hard stab to get it to go back.

 

ok I will try that. thanks

 

still stayed on. im going to rebleed the system brake doesn't seem real firm. may have air left hanging inside

 

Wiring intact? Even if it's hooked up it may be electrical.

 

Any chance you had the MC get low on fluid during install? You can't bleed air out of the MC in our cars, you have to bench bleed them.

The last time I changed calipers, I could not get the last little bit of air out by gravity or vacuum bleeding. I had to do the two man method to get that last little bit out. However, even with a little bit of air causing a slightly soft pedal, the switch didn't move in the proportioning valve.

 

You have to stand on the pedal really hard with the car running to get the switch to reset.

 

Shouldn't he have installed the line lock AFTER the proportioning valve? In the line that goes to both front brakes?
Maybe I tee'd mine together, like this:

 

UPDATE: got it all worked out. there must of been air in line still. re bled system and light goes out when hit brake pedal after line lock is activated. thanks for the help

 

Yes. He got it installed wrong and the dummy light is telling him he's a dummy.

 

Yup, the way it is plumbed in, it will trip the brake warning light each time.

 

no issues since, so maybe your dummy light is still on

 

no issues still. plumbed just fine
