    Parking drum brake up and running. I love it, would not want to be without it for jumping out of the truck on steep hills. The parking brake on my 1/2 ton pickup does'nt work nearly as well as drum brake on Suburban.

    Hey I have a question along these lines....so if you use a line lock can you leave it on for extended periods of time (just locking the front discs) w/o it hurting anything?
    As in holding constant pressure in the lines is ok to do?

    i wouldn't be surprised if it was hard on seals to do that for too long.

    The party line is that over time hydraulics WILL bleed down. This is the "conservative" advice, meaning that it would be irresponsible to say they're OK to use as they are not intended for long term parking. How long a time to fully bleed down will be a function of how good the condition of the seals are.
    This bleed-down is the reason that the FMVSS requires a mechanical parking brake.

    For getting out to check something (self-spotting etc.) I'd have no problem with it. For longer term parking I would not rely on them.

    so like if you are going to park on a hill or something...besides turning away from the curb you would prefer a more conventional setup like the tc brake Jess posted or regular drum parking brakes in the rear?

    Mechanical locks have been used on some wreckers since the 70's (maybe longer?) as standard equipment. I have one on my truck, one on my old bossed truck, and three wreckers that had them and never had one failure with long term parking. My truck is sitting right now with a mechanical line lock being used. It has been sitting since August and no probs. Yes I do have a back-up security measure in place just in case, since it will be there till this next August.

    Care to learn me?

    Mechanical are operated electrically? Does anyone have a link for these?

    Line locks are hydraulic? Do these use the factory plumbing?

    Are both of these types on the driveline?

    "as soon as shane gets em in, ill be running some of his ebrake calipers" - what are these all about?

    This is something I need to address by the summer if I want to participate in club runs.

    I think when people say line lock they are talking about this...basically it goes in line from the MC to the front discs...press the brakes...pull the lever...let off the brakes and the line lock holds pressure on the front discs (I think originally for burnouts) but I'm not sure...

    No, only a short period.
    The system is not designed to hold pressure like that.

    There are a few types of ebrake set ups. Mechanical Lever lock (most popular is the Mico Lock but jegs or summit has a cheep one too) there are electrically operated Hydraulic locks (I.E. Hurst Roll contol) and then there are standard Ebrakes (Disk and drum) the 1st 2 are installed in the hydraulic lines.

    BTW sweet transfer case brake.

    I would not use a line lock for a long time even if it Will do it its not intended for that and Can fail. I will not take that chance.

    I have an electric roll control/line lock that I use for a parking brake. It works just fine and I only use it when I leave my truck for short periods of time on steep inclines. It works just fine and I'm really glad I didn't drop the coin for el dorado calipers because I have been very unimpressed with them from the couple people I know that have them.

    To me, the bottom line is that you shouldn't really trust any parking brake type device. Always make sure your tires are somehow blocked or that your truck will not roll into anyone.

    The mechanical type just means that you turn them on and off by hand (mechanically). Will not disengage until you manually turn it off or depress the pedal again, depending on what style you use.

    Electric type just basically uses an electromagnet to push/pull the plunger to activate it. Only problem with these is that as long as it is applied it draws power from the battery. If used to long the battery will die and the line lock will release.

    You depress the brakes and activate the line lock then let off the pedal. This keeps the fluid from returning back thru the lines into the m/c causing the brakes to remain locked.
