JAMAR Park Lock

[milla85]

I was "surfing" Ebay and saw this for sale. Has anyone ever used a "manual" line apposed to an electric one? If so how did it work? Thanks - Nick

A buddy of mine uses a manual line lock in his CJ5.  It works pretty well.  Well, it works well enough that he blew a front axle when he forgot to disengage it. The one he uses is basically a forklift ebrake, they are also used on semitrucks.  Downside is they are spendy...~200 bucks thru napa.  I dont' see any reason why the one in your link wouldn't work ok.

Yup, I run a Jamar on my Cruiser. Even with my 5.38s, 3:1 case, small block and auto, It's impossible to unknowingly drive through the brake. It holds very well.

Sow with the "jamar park lock" i could use it as my e brake and get rid of the pull one on the lower dash? Would having it on say over night make seals blow out faster? Thanks - Nick

The Jamar is a "Parking brake," not an E-brake. E-brakes are for emergency braking as in no hydraulic braking necessitating manual braking.

I leave mine on everytime I park my rig in the garage. It sits engaged for weeks at a time and everytime I get back in the brake is still set.

Do you have the lines run into the cab for the brake?

[freds40]

Yup. I run them in by the cowl and go to my manual prop valve and then down into my Jamar on the floor so I actually set it with my foot, 1 less thing on the dash.

[Hottrod81]

Sounds like a good idea.  So it sounds like you ran the brake after your proportioning valve then?

[freds40]

Yup. Took a little extra time getting all the air out of the prop valve and the lock but it works great now. Also, originally I was a bit skeptical on the Jamar as far as someone "bumping" the brake pedal and unlocking it. If you set it right, you have to stomp on the brake pedal for it to release. I think it's a great setup.

[Hottrod81]

I am definitely going to look into something like that.  I was originally looking at a line lock, but the floorboard sounds pretty good to me and it keep the brake lines out of the cab.

Sorry to ask again, but could i get rid of the cable parking brake that come stock on my truck and just use the "jamar" as i would use the stock one? Thanks - Nick

Yes

It is your call on that. You will be the one to blame if it releases and runs in to another car or property. That said at work we have a 20,000lb forklift with a mico leverlock on it and it sits for months and the brakes are hard as a rock when we finely us it. Why do you want to get rid of the factory one? Why not have both just in case.

He might be wanting to run disc brakes.

[milla85]

Running a rear disk with out a e brake calipar. I know my brother has a line lock on his jeep and he uses it to start on steep hills when he is wheeling. How is the "jamar" depressed and realeased? could it be done with you finger or does it require more force than that becasue its not electrical.

[freds40]

Jamar is pretty slick. You depress the brake pedal then push down the Jamar knob. (definately able to do it by hand) then let go of the brake pedal. When you are ready to go, push down on the brake pedal and it releases.

[milla85]

Oh wow i didnt know it worked like that! Looks like i will get one of them, sounds pretty cool.
