Hydrolic hand brake - 6G Celicas Forums

Has anyone ever fitting a hydraulic hand brake to their 6G?
Is there any way to tap into the existing oil lines and isolate it to the rear callipers only or do I need to install a second calliper?

install a second set of calipers.

the hardest part would be to get a custom mount for the caliper. plus, you wouldnt want to NOT have foot pedal use when pulling on the ebrake if you went with an in-line ebrake

Just out of curiosity, why would you need that on a FWD car? smile.gif

idk what ray would be using it for, but I know a hydraulic e-brake could come in handy in auto-x to wiggle that rear end around the corners.


also Ill add. An inline E-brake wouldnt be bad really if you are just using it for what it is...a parking brake. But for heavy race (or drift) use, I would go with a dedicated caliper

Ray has an AWD car.....soooo that could be part of it.

If you wanted to go hydrolic e-brake the best route for a celica is a secondary caliper specifically for the e-brake,.

I have it inline, def get another set, the brake pedal over powers it if you brake while pulling the e brake, on the other hand it still works fine for me.

Be a man and buff up your e-brake arm. You could be like Pop-Eye. tongue.gif

Isn't it really bad to lock up the rear end on an AWD setup? I know it's a completely different car and completely different use, but for ken block, I know that when he pulls on the handbrake, it also disengages the drive shaft. Which makes sense since if you lock up the rear on AWD you'll end up binding stuff in the transmission or rear end.

205's have a viscous center diff that can take up the difference in speeds for a short time.

Thanks for your input guys. I suppose mounting a small calliper from a ST202 with a modified bracket to the rear hubs should be sufficient.

I thought the purpose of the Emergency brake was to have a mechanical backup in case the main brakes' hydraulic system failed. Also, how well will a hydraulic system last as a parking brake; you may leave the car sitting for days or even weeks with the hydraulic ebrake pressurized and sitting that long may allow the system to lose pressure.

You're right it's an emergency/parking brake, I've had the pleasure of having to use one as intended when my brake master failed... I think the reason for wanting a hydraulic one is to more easily break traction in the rear, usually for drifting. For a track car none of that is too much of an issue.

You can also use a seperate system from your main hydrolic....which is how its normally done.....

You could easily use a motorcycle caliper and master cylinder to achieve this.

My problem is that using the e brake as we do the internal shoes wear out way to quick, causing the car to roll when parked uphill etc...so keeping it in gear and with the new e brake i have no issues now of worn shoes as they are not used

NO! You need to pop the clutch in and hold the revs with your right foot while E-braking

speed in - > brake -> turn -> clutch in, brake out, pull ebrake -> blip blip, release ebrake, clutch out


the reason why gt-fours need hydraulic handbrakes is because the internal handbrake drum (just like that on brembos) is piss weak

e-braking while in-gear transfers alot of the braking force up to the front via the drivetrain
