thats the only way mine works too. just takes one after the button is depressed.

Ive also heard horror stories from many people about the jegs line locks...

This^^^^ I have a 69 camaro with drum brakes. It always holds when I do that.

Or like I am doing, ditch the shitty drum brakes for some nice discs!!

realy ? pushing after you engage the button ? that seems to me that the solinoid is bypassing ....i think.hell if it works thats great.i try to stay away from the house brand stuff if i can.its just worth the extra dollar to get the better part somtimes.

I pump my brakes up several times then turn on the line lock while my foot is on the brake. It seems if you do it after turning it on the fluid woud just hit the solenoid and not go into the caliper. The only way this would work is if there were a check valve in there, right?

I'm not doubting you, but that just doesn't make any sense :smt119 When you pump the brakes, the only thing I can imagine must be happening is you're lifting the needle valve and letting additional fluid pass through to the caliper. You might want a better line lock or be in need of a rebuild?

If you've ever taken a line lock apart you would see how the valve works, they are all the same. It is a needle type configuration like in a carb and when enguaged it simply prevents fluid from back flowing. It has a spring behind it so when you step on the brakes it alows fluid to pass and then pushes the plunger back. It is only magnetic and would never be able to hold against the pressure of the peddal being pushed.

So if you push the pedal after it's engaged fluid will pass through but won't come back out?

All the ones I've had apart are like that ,yes.

 

[horweenracing]

just kept from from flowing back is what I thought.

exactly.

 

[DARTH]

well i be damn.i learned something new today.thanks.im gonna try that next time to see if that works on mine.ive never had a problem engaging it after i hold the pedal.but im courious to see if it works.

 

[JP Racing]

sounds like you are having a brake pressure problem... possibly a weak master cylinder

 

[Road Runner Kev]

Or air in the line. Sometimes they are a bitch to bleed.

It does no good to pump against a closed valve, the fluid can't reach the calipers.

I have always pumped 3 times and engaged the solenoid on the 3rd pump.
