I want to set up a electric line lock on my 250 as a parking brake. I know not ideal but i think it would be perfect for my situation.
I had so many issues with my drums, and the parking brake never held. I upgraded to lugnut4x4 disks a few years back with elderado? calipers that have the parking brake. I was skeptical they would actually hold, but both lugnut and rough stuff said that they hold just as good or better the the drums.... Well they hold if im flat ground and thats about it... They are also a pain in the ass to set and replace the pads. I would like to change them to the normal calipers next pad change.

Im in FL I dont need a parking brake for long term. I always shut off and leave in in reverse (zf5) The only time use it is when i get out for a couple minutes, not enough to shut off and im not on perfectly flat ground. The calipers generally hold in that situation but i also need it to hold on a boat ramp. Right now i get the parking brake pedal to the floor, turn the wheels to the right, then lean out the door a toss a rubber wheel chock under the wheel and roll back on to it.
I know how to back a trailer, I know how to load a boat and im not that loser that waits till hes on the ramp to load and unstrap.
So I need the brake to hold 5 Minutes tops. Really less, because I will still use the chock and turn the wheel to the right. I just want it to hold long enough to get the chock under it.
I want to do the electric one so i dont really have to modify my lines, or have a valve on the floor.
Am I going to kill a boat load of nuns?:flipoff2:

Don’t do it. They get hot they stick bad things happen line locks should not be used as emergency brakes trust me I’ve already looked into this and just a lot of bad things happen. Abandon this idea you’re better off carrying around wheel chocks

This.

I’ve touched way too many line locks that were smoking hot when in use for a few hours. Literally hot enough to melt wires.
 
Theres no way its more dangerous then leaning halfway out my door to be able to swing the chock under the tire, with the truck angled to run me over if i slipped.
we are talking maybe 30 min at the most even if i got a manual one that wouldnt do it?
 
Try it and report back.

Somewhere way back in teh internets it didn't work out, and the tale stands to this day.

Brake pedal stick cut to length?
 
Is something like this possible? Do these work well enough?

so millions of vehicles factory brake can hold a loaded boat, trailer and 1 ton truck on a steep boat ramp without slipping even when the boats being powered off or on? I doubt it unless the auto trans is also in park.

After having to mess with these calipers for way to long to many times i have no hope in them holding a truck on anything more then a slight incline. worse case the line lock fails and i forgot the chock, then the truck jackknifes the trailer or hits the dock. I never get out without turning the wheel.

the micro cable lock looks interesting but i dont see a part number or price anywhere.

You know, I have quite a bit of experience with that. And the answer is 'yes'. Unless maybe you're forgetting to untie the boat when you're powering it off.
 
Just get some electric parking brake calipers

Linear actuator parking brake

Anyone messed with a remotely actuated parking brake? I’d like to have a parking brake again, it sucks to winch when I have to sit in it and hold the brakes or put it in gear with the engine off. I’m putting a wider axle in my 4Runner and it seems like it would be simple enough to mount an...

One of the ramps I use most often if pretty shallow and the deeper you go the shallower it gets, i really have to work the boat side to side in reverse to get it off thats after slamming the brakes to get it to slide back a couple feet. Probably the same as it being tied

Yeah you have never actually used a factory parking brake. Msha puts our service truck on the steepest grade and the brake needs to hold the truck.

I need to put a mechanical driveshaft brake on my trucks. Find me a kit for a 2000 f550 4wd trucks.
 
I have a All Pro driveshaft disk brake on my runner that's worked ok through the years. It holds on an incline if it's adjusted just right.

Driveshaft disk brake with a Tesla electric caliper is my next project on it.

You for reals can go to the boat ramp and can't find a friend to go with you to help?
That seems to be when I have the most friends:laughing:
 
I also live in Florida and have this dilema. I tied a rope to my chock. Set it down with the rope and back up to it. When you drive off pickup the rope and the chock comes with you.

Does this not drain the battery? the park brake set for extended amount of time

Amp load based disconnect is my very basic understanding.

So they unlock with electricity applied then? Similar to air brake cans. Im putting together an old square with a manual, so Im shopping for options. Right now Im leaning to the 205 output caliper. I dont want one more electric thing on that truck than is necessary.
 
In for the fix. My 95 f350 will hold the ramp with the flat bottom, but I wouldn't trust it with the Cobalt on.

My sketchy understanding from the other thread is that all electric calipers have a stepper motor to screw the pressure down, then use no juice once applied.

Look at a mico brake lock. They are designed for service trucks and similar to a line lock.

I had one I was going to put on my f250. Wonder what happened to it

^this , we used the micro brake locks on a lot of equipment. No drama


I have a line lock on my vette, it's not a parking brake.

Shoot, then just leave it in drive at a fast idle.
