Hydraulic ebrake option for big brage upgrade?

[AndyMac]

Has anyone installed or considered using a hydraulic emergency brake instead of the separate cable operated caliper?

I like the look of a single caliper in the rear as opposed to two.

Here in the US of A, at least in my jurisdiction, the e-brake must operate from an independent system than the primary system. In other words, complete loss of hydraulics at any point in the system will still allow the emergency system to operate the pads. If you look at how e-brake systems work you'll see that is the case. Much easier to do that mechanically than with a second hydraulic system. You may be able to get away with not having that level of function in Canada.

Good points Dave. I was also thinking about the legality of not having a separate e-brake system, but in our motor vehicle act, it does not state that the park brake system must be a separate system, just that it holds the vehicle from moving.

Legality aside, I don't think it would be too much of a safety concern in our setup. For the complete braking system to fail, both the front and rear lines would have to fail at the same time. If the master cylinder failed completely, there is still fluid in the lines to the rear calipers and as long as there is fluid between the e-brake and rear calipers, your e-brake will still work.

I had that type of set up in my modded out GTS, and to be quite frank, I didn't like it, I had to press the brake down and then I pusher a line lock button down to lock up the rear brakes, theoretically it worked but everyday application was a P in the A, I always left the car in gear anyways so it was not much of an issue when or where I parked but I never felt it was overly safe.

This is the setup I was thinking about, it would retain the stock e-brake handle attached to a master cylinder. The MC would be inline with the rear brakes.

I am lost as to why one would convert a very usable mechanical brake system to hydraulic?

In order to upgrade to the SRT 14" rear brake setup, (Daves Big Brake Upgrade), you need to purchase and install a second caliper that acts as a mechanical park brake only. (since the SRT calipers are from the front of the SRT10's and do not incorporate an ebrake)

Besides the 700 bucks for the dedicated ebrake setup, it's not as clean looking as just the SRT10 caliper. It's a personal preference I guess, I just think it looks cleaner without the separate ebrake.

Even the SRT-10's have a separate rear E-Brake. The DBB kit does not use 4 front calipers, it uses all 4 corners correctly. It does not however use the SRT-10 e-brake, it uses an aftermarket type instead, which are similar.

Yep and instead of using the rear gen 3 rotors you have to use front gen 3 rotors for rears on your gen 2 upgrade...

Some promods use em for staging and burnout. I think some drift cars use em too. Do a search. Good chance the Mopar Drift Viper driven by Sam Hubinette had a hydrolic E-brake.

Sorry, I confused the option of using the old front calipers and rotors in the rear when upgrading just the fronts to the SRT's.

Yes, near butt ugly.

Agreed, the faux Sneaky Pete graphic is cheesy.

BBD did that because of copyright issues. The flip side of that non-Chinese non-junk part is that it is very well made and engineered. I'm sure the Chinese cheap version with the illegal non-faux logo works just as well.

I put a big brake kit on a Gen 2 coupe of a friend of mine. I dont recall the brand but it was purchased through Jon B.

The kit used the original Gen 2 rear caliper as the emergency brake caliper. The kit had you install a specuial fitting where the original brake line went, and the rotor was relocated more rearward. It used the original emergency brake cable and was pretty ingenious how it all came together. Call Jon B. for more details.

The BBD e-brake caliper also uses the stock cable etc. Ingenious? Yeah, BBDave was that guy.

Although the OP is pursuing NO e-brake caliper the option you refer to may be more stealthy and "factory safe." Probably StopTech kit.

Here's the back of the BBD setup.

Another possible option comes from the street rod guys. It is a small diameter rotor that fits up between the end of the drive shaft and the diff. There is a bracket that holds a small mechanically operated caliper that serves as the emgency brake.

Drift cars have massive extra calipers on the rear that are hand/hydraulic operated.

I would not go with a hydraulic setup as they tend to leak down over time, vs a ratcheting cable brake like is what is on most cars for a parking/emergency brake.

If someone doesn't like the BBD sneaky pete like logo, there is this stuff called paint, that can be filled into the engraved logo there

Hydraulic e-brakes are fun for things like J-Turns and drifts, but otherwise, they're not too safe for every day use. Think of it this way - would you want to park your car on a steep hill overnight with a hydraulic e-brake? It doesn't take much for fluid to leak while under constant pressure, and even a slight leak will decrease the holding power of the e-brake quite a bit. Even if you leave your car in gear, you run the risk of finding your car in a new location when you go out to get it in the morning...

The BBD logo does not have to be put on the e-brake caliper. Mark at IPSCO (who actually designed and makes the parking brake kit) will put anything you want on there. He makes and sells e-brake kits for a multitude of applications.

The stoptech rear e-brake kit is useless. Will only hold on a level surface and when no one leans on the car. Will pass inspection however. GTS Bruce

Same as the DBB kit. Those are really "spot" calipers, which are designed to hold a stopped car on reasonably level ground, from rolling away. They are not designed to stop a vehicle in an emergency. But like you said, they pass the window sticker test.
