Bleeding the brakes
« December 11, 2017, 20:03:40 »
Hey guys, I have a Hyundai i30 2011 FD 1.6. I want to bleed the breaks on it, however, which wheel do you recommend to start with first? every person on youtube says something different. Also, do you recommend the one person method or the two person method? Which is the most safest?
And is DOT 3 better than DOT 4 break fluid or scrap all that and get the genuine Hyundai brake fluid?
And is there torque specs for the screw that you take off to bleed the valve?
Many thanks

According to repair manual the bleeding order in i30 is:
1. Rear right
2. Front left
3. Rear left
4. Front right

I've always used 2 person method (as it is so easy if there is second person available) and dot 4. Dot 4 has higher boiling point than dot 3.

Left hand drive or right hand drive?
The method I've always used has been work from the wheel farthest from the master cylinder. If this method is used, obviously it matters whether or not the master cylinder is moved when the steering column is.

Location  is same for all. Have you checked out the setup we have? Our pedal is like a driving school slave setup where our pedal is attached to a steel tube that's mounted across the bulkhead and attuates the master which is mounted in front of the passenger.  LHD would be a traditional pedal box I suspect

I thought that was the case on my FD but couldn't remember for sure.

With previous cars I also used the distance method. It was a new thing for me with i30 to bleed front left before rear right. Could it be that first two are in the same brake fluid circuit? I would guess the distance method works with i30 also...

I've never thought much about the sequence, just went ahead. Make sure to bleed at least 0,25L at every wheel.

I always just do it by myself. When I have to have the brake pedal hold down to the floor I use a piece of wood or whetever handy, to place between the brake pedal and the seat, then slide the seat forward. Now brake pedal is at the bottom and you can get out to close the bleeder screw.

Doesn't matter, just make sure it's DOT 4

A good video is this: . He shows you the two methods one with the one person method (near the end) and the other is with the two person method. And it seems like the one person method is much easier than the two.
Also, you don't have to do that thing with the chair your to close the bleeder.
Look at how he does it on his own.
Maybe your life would be easier the next time you bleed the breaks?

alaster do you know the diameter of the bleeder head? So a vinyl tube can fit over the head tightly without letting air in?

Hoses for windscreen washer system normally fits. Buy the clear type so you can see if there's air in the system.
