Guest scarylarry Posted April 1, 2011 Share #1 Posted April 1, 2011 Tonight a friend called and said his front brakes are lock up both sides, so I said master cylinder is bad or the caliber pistons.. He was blocking traffic so we called a wrecker they towed to a parking lot in a safe area. Then I notice some wiring hook to the master cylinder trace the wires back to the inside to a toggle switch flip the switch and brakes unlock. He just bought the car and that switch was use for burn outs when, I guess when you are racing.. This is the first I ever seen or heard it. Anyone ever heard of this?

royalstar09 Posted April 1, 2011 Share #2 Posted April 1, 2011 Yes I have seen, and installed similar systems. I have put electronic brake locks on rollbacks, and wreckers. I prefer the manual ones, but hey customer gets what customer wants. What kind of a vehicle is it? Link to comment Share on other sites More sharing options...
scotty Posted April 1, 2011 Share #3 Posted April 1, 2011 sounds like a 'mico lock'. I have seen them installed on old grain trucks. A lot more effective than the POS driveline bake when unloading on a hill. I am surprised they still make them. Never seen one installed in a passenger vehicle though.

Reddog170 Posted April 1, 2011 Share #4 Posted April 1, 2011 I liked them when I was racing, get better stats with them. Did not think that anyone would leave one hooked up when they sold the car for street use though. Shaun Link to comment Share on other sites More sharing options...
Keemez Posted April 1, 2011 Share #5 Posted April 1, 2011 AKA line-lock. Very common in cars that are drag raced. Useful for burnout stage- it simply applies the front brakes only, leaving the rears to turn freely for burnout. Link to comment Share on other sites More sharing options...

royalstar09 Posted April 1, 2011 Share #7 Posted April 1, 2011 05 mustang GT That is a good indication that the car has been rode really hard. Bet a guy could find where a small NOS bottle was mounted if ya looked hard. There is only one reason for that to be installed. Link to comment Share on other sites More sharing options...

naturbar Posted April 1, 2011 Share #9 Posted April 1, 2011 someone already mentioned it is a "line lock" - you will find it mounted in series with the front brake line at the master cylinder. if it has an inline fuse simply remove to prevent accidental activation, or cut and tape one of the wires to the solenoid (line lock). see pic below..... file:///C:/DOCUME%7E1/Rutan/LOCALS%7E1/Temp/moz-screenshot.png Link to comment Share on other sites More sharing options...

Cause there is no brake lights when this is engaged Link to comment Share on other sites More sharing options...
