jp_89 New Member 6 Member For: 10y 3d Posted 10/03/15 05:30 AM Share Posted 10/03/15 05:30 AM Hello my names john and im a newbie to this forum.I have an issue that someone in here might have answers for.I recently bought a complete set of slotted rotors, calipers (Brembo 4 piston fronts and PBR single piston backs), brake lines and mounting brackets off a bf gt to install on my bf xr6t ute thinking it would be a simple install.after I cleaned up and re-sprayed the calipers because of plenty of scratches on the faces I installed them. (pictures included below)I had no problems installing the rotors and calipers apart from the rears which gave me a bit of trouble taking off the old rotors and the brake lines off the gt were too short so I ended up just using my rear brake lines already on the ute.I then started the bleeding process with another person one person pumps the pedal 4 times then holds while the other cracks open the bleeding point then closing and repeating till all the air bubbles are out. we started bleeding from the passenger rear, drivers rear, passenger then drivers side. all while making sure the brake fluid level is kept topped up.Even after all this process the brake pedal is still a bit soft and pushes down right to the floor.Im wondering if I have missed any step or had to install another step for these brakes to work on the xr? I have been getting mixed answers from people I have asked as some tell me I need to replace the master cylinder (I thought all the master cylinders on BF models were similar) and others tell me theres a certain way to bleed abs brakes. Thanks in advance for all your help and guidance. Link to comment Share on other sites More sharing options...

Alternate inside outside on each caliper more than once, I think its ment to go, outside then inside, dont think it really matters but just do it a couple of times. Also its hard to make out from those photos of the rears but your brake line looks to be sitting at the top of tge caliper? Nipple should be at the top. Wrong sides maybe?Also ive never been this unlucky but did you place something under the pedal to stop the pedal going to the floor? Apparently letting the piston in the master cylinder travel to far can stuff the seal. Apparently... Edited 10/03/15 06:52 AM by barnz Link to comment Share on other sites More sharing options...

Nipple at the topTake a bottle of water and put a pin hole in the top, turn it upside down and squeeze, air will only come out once the water is gone, air being lighter will always rise to the top Edited 10/03/15 06:57 AM by barnz Link to comment Share on other sites More sharing options...

That was just an example of what happens to air mixed with liquid.You need to undo the calipers and lines, swap sides and re bleed, brackets shouldn't need changing.What I mean is the calipers are on the wrong side of the car! Not change the fittings around.. Edited 10/03/15 07:15 AM by barnz Link to comment Share on other sites More sharing options...

Here's an illustration I googled for ages to find and then cleaned the watermark out of (mostly) 1 Link to comment Share on other sites More sharing options...
