Technical e brake

hi all im looking for a driveshaft mount ebrake assembly that fits a 12 bolt ??

 

There is nowhere on the housing to bolt it to.

 

Ok then it looks like ill have to replace the rear calipers to accept cables and put in a floormount!

 

https://nlrderbyparts.com/product/pinion-brake-kits/ says it will work with 12 if flipped. select the 10 bolt.

 

Why don't you make a "Fly-off" style hydraulic handbrake like used in competition rally cars.
All you need is a single m/c with remote reservoirs and you plumb it inline.
In the relaxed position the hydraulic fluid flows through as if there was no m/c at all.

When you pull the handbrake the M/C blocks off the lines upstream and it works like a normal handbrake.

 

This link might help - or not.

thats a great idea thanks !!!

 

Using a fly-off brake is ok for racing applications but its no longer an ebrake. You risk gradual loss of hydraulic pressure when parked AND more importantly its no longer an emergency brake. A failure in the foot brake hydraulics may also fail the e-brake as it shares some of the the same circuit.

 

What is stopping you just using conventional equipment?

 

it is built as a drag car . with racing equip rear disc brakes !

 

okayyyy!!

 

How thick are the rear rotors?

 

theres no place to bolt on or attach cables on these calipers

 

not sure ill have to measure

 

Do you know what calipers they are? Can you post a picture?

The reason why I ask is that there are mechanical "spot calipers" that can also be used, in addition to the hydraulic ones.

 

^^^^^You don’t say what your rears came from or aftermarket. Many were like that before they went to the inner shoe.

Wilwood sells both a spot and a smaller than normal pad style. The pad style fit an .800+“ rotor. I think the spot style is for the non-cooled narrow disc.
Call them and ask how the mount. Their tech line is great IF YOU KNOW EXACTLY WHAT YOU HAVE so they can work with it.

Googling ….rear disk brake emergency brake will give option. On our 40 Chevrolet ex drag car my son used a lokar handle between the seats.

 

Not knowing what you have for calipers now it is near impossible to suggest replacing your calipers with ones with a mechanical park brake. That setup that Fastcar53 posted in post 4 looks heavy as all get out and would add a lot of weight to the axle. Unsprung weight you don't usually want.
Wildwood has some add on mechanical calipers that might work plus a batch of calipers with built in park brakes. I'd spend some time snooping their catalog and see if there was a simple and viable solution. They have one "electronic" park brake caliper that might do what you want with a simple bracket.

ok i see thanks ill get a pic !

 

What a load of absolute bullshit!!
If you risk gradual loss of hydraulic pressure when parked, then those components don't belong on the vehicle in the first place.

We use hydraulic handbrakes on trailers [a mechanical ratchet overriding hydraulic surge brakes]


On my last trailer I left it parked for over 12 months with the handbrake pulled up and there was no loss of fluid anywhere.
One Caveat here...... I packed the M/C with rubber grease to protect the cylinder walls from the exposed atmosphere because I live near the ocean.

@aircoup The term "fly-off" is actually misleading , that's why I said "Fly-off Style" [Fly-off refers to the removal of the ratchet mechanism for rally cars, but the hydraulic handbrakes still work the same]

We [in NZ] don't use the term "ebrake" but use "handbrake or parking brake" instead.

A true "emergency brake" is the actual dual brake system [either tandem or dual M/C's] for safety I always recommend using a dual system.
The hydraulic handbrake does not affect the Fr/Rr brake bias in any way.

If you want to go really simple [for temporary parking] you could simply add a switch activated "line-lock" solenoid into the brake circuits .[this would require initial pedal pressure, and could drain the battery]

But the hydraulic handbrake can be used in a moving situation [stunt driving ]
You can mount the inline M/C anywhere , eg: on the frame underneath And use a lever with a conventional handbrake and cable.
This would prevent having an ugly handbrake with a nice interior [depending on the theme of your car]

 

Can anyone ID this shifter for me? It has the Ford reverse lockout.....for a car with no console? It seems to have too tight of a curve in it for a bench seat car? ....Thanks for any help....

 

Please start a separate post for this.

 

Such systems are not all that common in the US, for a passenger car, or light truck parking brake.

So not all that common that I have never seen a locking one in use.

These do not comply with US Federal Motor Vehicle Safety Standards (FMVSS), which require that the parking brake actuator be a separate system.

It is a delicate legal ground, and that might be why they are not common here.

If he's trying to get the car legal for street operations, depending on his state's laws, a hydraulic parking brake might not pass inspection.

 

Some GM (I know there are Eldorado calipers) that have a cable operated parking brake provision. It might be worth looking into.

 

They came on a few cars, in both pre-metric, and metric versions.

Rebuilt ones from the parts store don't always have all of the lever parts on them, because it is expected that you are replacing existing ones.
