Dang air in my brakes

[pooperscooper]

So I accidentally completely emptied the brake fluid reservoir and now there seems to be air on the whole system, even though I did tap air off all the brakes.

Any ideas?

Bench bleed the MC to get it out. The subie MC is angled up slightly, so if the reservoir is emptied, it'll be impossible to get all the air out without taking the MC off the car.

aw man. I'll do that.

Thank you!

I wouldn't recommend bench bleeding, it's so difficult to do with these that even if you get the air out on the bench you're going to make a huge mess and introduce air while trying to hook up the brake lines to the MC.

To MConte05's point, if that's a concern just jack the rear of the car higher so air isn't trapped. However, I have never done this and have had bone dry MC's a few times. I recommend bleeding as normal, and then bleed with the engine running so you have the added pressure of the vacuum assist.

My normal bleeding procedure is to slowly pump the brake pedal around 10-15 times, hold on the last pedal, then have a helper open the bleeder, and close it when the pedal is on the floor. Repeat this process several times per wheel in the factory bleeding order. I usually will do this first without the engine running and then do it one or two times with the engine running.

You may need to bleed one more time after driving the car a bit if the brakes feel spongy. However the above method has worked for me every time on multiple cars.

Thanks for the tips.

I've already gone through and bled the brakes on every poont multiple times, always with the car running though.

Also I have no Idea what the factory bleed order is.

The order is right rear, left rear, right front, left front

basically furthest to nearest the master cylinder.

This is for non ABS systems, I think there's bleed screws on the abs pumps.

Check out speed bleeders for ease of bleeding the brakes by yourself. Awesome investment.

[cj91legss]

That's a good point!

To add to that I bought a pneumatic bleeder from harbor freight. It hooks up to the caliper. You put the provided bottle upside down in the master cylinder and squeeze the trigger at each caliper. Pretty slick and only takes about half an hour for all 4 corners.

It just hooks up to an air compressor

CJ,

The FSM order is RF, LR, LF, RR.

The big thing is you bleed each circuit together. Since the brake system uses a diagonal brake system the RF & LR are tied together and same goes for the LF & RR. So if you do the furthest first, you should do RR, LF, LR, RF.

I've always followed FSM order.

Well shit... I did it all wrong lol.

OP Ignore me, I gave false information!!

Now I've got some garage work to do because that might answer a concern I have had lately.

Haha, thanks all of you for the help. Gotta love this forum

I will test the factory bleeding order in a few days and we shall see if the air goes away
