I cannot seem to get the brakes to bleed no matter what I do. I am doing it using the method in the how to thread, but the pedal remains soft no matter how many times I go through it. This is not the first time I've bled the brakes, but it is the first time I have had this problem. Does anybody have any insight as to what I could be doing wrong?

Check for a leak in all of ur lines

Is it possible there is still air in the lines?

What is the procedure your following? It's a two man job if your using the conventional method, a set of russell speed bleeders for the rear calipers can help immensely if your short handed.

Speed bleeders are great, I still try to have someone help just as a precaution. Also curious how op is doing this.

is it pulling fluid from the res?

If that is what the OP is using to bleed the brakes then he will never get the air out lol I spent 120 dollars buying that power bleeder and all the fittings for my car, and threw it across the street after 20 minutes of it leaking past the cap around the reservoir and putting air into the system. It's the biggest piece of **** tool ive ever owned.

I bought a power bleeder u hook up to compressed air, it took a while but it did the job, and was very easy. was like 34 bucks. good money spent

I am using the 2 person method. There are no visible leaks, I am going in the right order and fluid is coming out (not air).

rear pass, rear driver, pass front, driver front? Your pumping the pedal up, holding pressure on it, opening the bleeder for a second or two, and closing it, and then pumping the pedal back up again?

^^^For brembo calipers, do you have to bleed both inner and outer?

I used the power bleeder listed above. You do inner first then outer for the Brembos

I did have some issues finding the right spacer for the cap. Once I got it to seal it was so freaking easy.

^^^^okay thanks, now do you have to bleed all 4 corners when just removing the front 2 calipers?

Well I did my brakes on a lift, but I did have to remove all wheels. I went ahead and used the power bleeder and bleed all four corners and replaced with new fluid at the same time.

With the order of bleeding I would do all 4

I miss my OEM wheels since I could bleed the brakes with the car on the ground reaching through the bars.

OP.

Ive never had an issue but sometimes it takes a good deal of time.

This sound like it should be made into a "How to"

I added info to the rear brake thread, but nothing about bleeding.

But here they are: get power bleeder pump system. Add a good amount of fluid to the pump if you are adding new fluid. Find the correct spacer with the kit that will fit on the stock resevoir cap snugly. Pump bleeder to 10 psi or so and mach sure that it holds pressure. This will insure the cap is tight and there are no leaks in the system. The seal at the cap was my main issue initially. Then you begin bleeding. I went ahead and put new fluid in. Bleed each corner until new clean fluid comes out.

I'm no mechanic and took my time. Was simple.

Good info but that last one should be LF

Thanks yeah

I had this same issue man. try resetting the position of the rear calipers. when I did it it made the pedal feel hard again!

Take both calipers off. Use a Needle nose plyers and screw in both calipers until they cant go no more. Grease pins and put them back on. Go inside the car and lift the ebrake a few times.. Start the car take it for a ride.

Let me know if that helps.
