Bigshoes Posted March 31, 2015 Share Posted March 31, 2015 last weekend i swapped brembos and SS lines onto my 08. made sure the fluld was topped off and started bleeding them in the correct order PF, DR, DF, PR and using both bleeder screws. I have fluid coming out of the bleeders but no pressure it seems and the pedal is almost non existant. Ideas? Link to comment Share on other sites More sharing options...
whitetiger Posted March 31, 2015 Share Posted March 31, 2015 first, the correct order is PR, DR, PF, DF, and if at any point the fluid went too low in the master cylinder, then you will have to bleed that as well. make sure the brake lines are not leaking anywhere. under booster pressure, even a small leak will make the pedal drop to the floor. how exactly did you bleed them, just a gravity bleed or did someone help by pumping the brake?

That is the incorrect order according to the FSM. Correct order is PF, DR, DF, PR.

whitetiger Posted March 31, 2015 Share Posted March 31, 2015 ^ok. ill concede to that, though i was always taught to start with the caliper farthest from the MC(with the longest brake line feed) and move closer. Link to comment Share on other sites More sharing options...

whitetiger Posted March 31, 2015 Share Posted March 31, 2015 either way, you cant effectively do a bleed without either a pressure bleeder or a friend to pump the brakes. so im curious how the OP did it. Link to comment Share on other sites More sharing options...

Sure you can. You can gravity bleed them just fine, some folks even recommend that as the best method.

whitetiger Posted March 31, 2015 Share Posted March 31, 2015 a gravity bleed can be messed up very easily, especially when you have added new brake components, or have fixed calipers with 2 side to bleed. And as i said above, if you let the fluid go too low in the MC, you might have to bleed that as well. Link to comment Share on other sites More sharing options...
whitetiger Posted March 31, 2015 Share Posted March 31, 2015 And also if air got in tot he MC, it can get in to the ABS module which can only be bled using the SSM to trigger the bleed function. Link to comment Share on other sites More sharing options...
Moderators BarManBean Posted March 31, 2015 Moderators Share Posted March 31, 2015 Fair enough, fairly simple to make sure the MC doesn't get low tho. Either way I'm pretty fond of the motive bleeder, makes it quick and idiot-proof. OP, I would suggest a quick rebleed for starters. Also recheck for leaks, although that should be pretty obvious at this point.

Bigshoes Posted March 31, 2015 Author Share Posted March 31, 2015 I had a friend pump the brakes while I worked the bleeders. I can not say for certain if the MC went dry. When I filled all my fluids before starting (reinstalled turbo so antifreeze also) it was getting dark so I didn't notice if it was out or not. To add I also have no pedal at all. After my buddy left I put the wheels on and while still on stands got the wheels turning to see if the brakes would stop them. Im not getting enough pressure to the pistons to even have the brakes stop the wheels. Pedal is pretty much non existent. Pumping it does not bring it back to anywhere near what it should be.

starionesir Posted March 31, 2015 Share Posted March 31, 2015 How long did you bleed each caliper? If you stopped when you started seeing fluid you could easily have more air. And stupid question but you do have all the bleed screws facing upward correct? Link to comment Share on other sites More sharing options...
Bigshoes Posted March 31, 2015 Author Share Posted March 31, 2015 Yes all bleeders are facing up. I went over the brakes twice. No burping in the fluid coming out when bleeders were open. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
GTEASER Posted March 31, 2015 Share Posted March 31, 2015 And on the front Brembos you did the inboard bleeder first and then the outboard, correct? If you only filled the reservoir one time, you clearly did not bleed enough, you should have had to fill it up at least 3 times from almost empty. Pumping (5 times), holding, open, closed, release, repeat...right?

Bigshoes Posted April 1, 2015 Author Share Posted April 1, 2015 Going to try and bleed the MC tomorrow after work with a buddy. Has anyone ever gone this route with having air stuck in the ABS module? Trying to see what my options are for tomorrow. Commanding Sequence Control Without the Select Monitor You can also command Sequence Control without the Select Monitor. To do this, with the ignition switch “Off,” ground terminals 3 and 6 of the diagnosis connector, using the connector’s grounding wires. Turn the ignition switch “On” and, within a half second after the ABS warning light goes off, depress the brake pedal and hold it. The ABS will go into Sequence Control and purge air from the HCU.

Bigshoes Posted April 2, 2015 Author Share Posted April 2, 2015 Well after 3 more hours of bleeding i finally have a pedal. First time in 4 weeks the car comes off the jack stands tomorrow! Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
starionesir Posted April 2, 2015 Share Posted April 2, 2015 So what did it end up being? Just not bled long enough or air trapped in the abs module? Link to comment Share on other sites More sharing options...
Bigshoes Posted April 2, 2015 Author Share Posted April 2, 2015 I'm going just not bleed long enough. Went threw 2 big bottles of fluid and used a pneumatic bleeder along with the old school bump and hold method.

whitetiger Posted April 2, 2015 Share Posted April 2, 2015 yep, brakes need to be bled like hell before they come back to firm when installing new components. Link to comment Share on other sites More sharing options...
