Helterbot Posted December 2, 2021 Report Share Posted December 2, 2021 My car has almost no pedal pressure. I bled all 4 wheels and I was eventually able to get the air out, but for whatever reason I can't seem to get all the air out of the module on the passenger side under the hood. My friend and I spent about 15 minutes trying to get the air out, and we refilled the reservoir 2 or 3 times, but there is still air. I'm not noticing fluid anywhere, but my reservoir was empty when I first opened it up after sitting for 4 years. Any idea what might be causing this? I remember someone offered a kit to eliminate this, but I think that was quite a few years ago now. Link to comment Share on other sites More sharing options...
Turbo Cary Posted December 3, 2021 Report Share Posted December 3, 2021 When I deleted my ABS module from the CQ it was filled with a nasty gunk inside of it. Chances are that's probably why yours is no good. All you need to do to eliminate it is take the line from the master cylinder to the ABS module and route it to the proportioning valve under the master cylinder. You can get brake line and cut/flare it yourself or just loop the hard line you have already a bunch of times until it can connect down there. I did the build my own method. Another option is to have someone make you a steel braided line with the right length and fittings. FWIW the ABS doesn't really do well on these cars anyways and you can free up a bunch of room in the engine bay by deleting it. Link to comment Share on other sites More sharing options...
tux Posted December 3, 2021 Report Share Posted December 3, 2021 Did you follow the correct procedure to bleed? It's this order Passenger Rear, Driver Rear, Brake Module, Passenger Front, Driver Front Link to comment Share on other sites More sharing options...
tux Posted December 3, 2021 Report Share Posted December 3, 2021 If the above doesn't work, there could be bad o-rings in the hydraulic cylinder. you can take the cylinder out and clean it up. but if that's the case, you may have brake fluid in the vacuum reservoir area.

Helterbot Posted December 3, 2021 Author Report Share Posted December 3, 2021 I'll try bleeding everything again and inspecting that cylinder. Link to comment Share on other sites More sharing options...
Helterbot Posted December 3, 2021 Author Report Share Posted December 3, 2021 I decided to replace the master cylinder. We reverse bled everything, and so far everything seems good. Link to comment Share on other sites More sharing options...
