Line Lock?

[k5blazinredneck]

Does anybody know a good line lock kit for a 1990 k5 blazer? I did a 3/4 ton axle swap and need a parking brake to pass inspection. Also any instructions on installing it would be greatly appreciated! Thanks in advance. -Aaron

better check as parking brakes / ebrakes for inspection tend to be separate from service brake system .

and there all around the same and include directions . its a inline item .

but line locks are not for long time left on use . even tho some say they have .

there is better units that are mechanical and made for parking / holding use. and some come with buzzer option if the pressure drops .

Im pretty sure the parking brake also has to be completely mechanical. Something about having the ability to apply the brakes incase of complete hydro brake failure.

I liked the idea of a "pinion" brake ,they are way more effective thanks to the gearing in the diff...

They sell a similar thing for a NP205 ,I saw one for sale on here recently..but I suppose they could say thats not acceptable either,because if the driveshaft came off you'd still have no brakes.

...but if thats the case,why do they let school busses and big box trucks have the drum type ones on the tranny output shaft for parking brakes?..

Just hook up the cables, problem solved?

That's what I did anyway...

I've got disc brakes in the rear though.. But I don't have the Cadillac eldorado calipers and I was seeing if there was any way around getting them?

In that case, I have no answer for ya. Carry on.

There are ball valve style ebrakes that are not the same thing as an electric line loc. They're essentially the same thing as putting something heavy on the brake pedal. I don't know about your laws, but AKDOT has allowed us to use one on a medium duty scissor lift with a 42' bed for the last 24 years. The ebrake cables would be insanely long so we do it that way, and has worked flawlessly. We always chalk the tires (law) and when its parked at the shop we release the valve and chalk the tires to prevent extra stress on the system, and I have never had to pull the truck off the chalk to pick it up, even when the valve was on for 12 hours on a hill at a job.

I wonder why no one has used electric actuators on rear disc calipers E-brakes?..seems it would not be too hard to mount one up so it would apply the E-brake lever on the caliper just as a cable would,and it would not be as likely to freeze up when not used often, like most typical cables when you have "park" in an automatic..

I rarely use my E-brakes for that reason,and the cables seize up in a few years..even if I oil them..and replacing e-brake cables ranks among one of the worst PITA jobs to do on many vehicles..not cheap either,and getting the correct cables can be a chore too..

...(my Contour has a short cable from the handle in the car to operate the other two--and its a "dealer only"one,if its still even available,and riveted to the car too,making it really suck to replace--you must also drop the exhaust down and take tin covering off the tunnel to get at the rear wheel cables too--250 bucks to pas inspection for new cables and to have them put on--and the exhaust probably wouldn't survive being removed also!--if I hadn't found a place that let it slide as-is I'd have been boned--it works, but wont release without some persuasion at the calipers!)..


I think some newer vehicles have gone to "electric" parking brakes...they aren't hydrailically operated,so I dont see why they wouldn't accept them at inspection time..
