Good job. Btw, do you have a video on the procedure on bleeding the brakes. You said there is something you have to do if you have abs. I have 08 f250 Harley Davidson. 2 master cylinders in 8 months. Last time front driver side locked up. Starting over. New master cylinder, calipers, rotors and I am replacing the break line on the front driver side. Don't want to keep doing this.. Any recommendations will be appreciated.
There's an ABS Bleed Procedure that the BCM does, but you'll need a laptop, OBD II Cable or Bluetooth Adapter and Forscan. Other than that it's the normal bleed procedure. Since the diesel trucks don't have vacuum assist, it uses Hydraboost (the pressure from the power steering pump) to assist the brakes. I always do the power steering bleed procedure as well when bleeding the brakes, albeit probably overkill.
Mike, After watching both this video (where you don't remove degas bottle) and your hydroboost video (where you DO remove the degas), quick question: After doing both procedures do you feel I can get the Hydroboost out without removing the degas? My master cylinder is fine, but my Hydroboost needs to be replaced. I am thinking of going about it without taking out the degas. It certainly appears (in this video) that I can get the Hydroboost out with the MC out of the way. But I am hoping that I can just unbolt the MC from the Hydro, but leave the brake lines connected and move the MC out of the way to wiggle out the Hydro. Is that possible with the degas bottle still there? Or not enough room?
I’m curious about the vacuum tool you use to bleed the brakes? Also I’d like more info on the handy ratchet tool. Could you please give us the model a name brand? Thank you. Love the video
Great video! I have been working on a project past couple of days and I think my last step will be to replace the master cylinder. My truck is a 5.4 L 08 F250 Supercrew w/ manual trans. It didn't come with the OEM TBC but has the towing package, the wiring, and I added the controller and I enabled it in Forscan already. I'm able to adjust the gain and it shows "Trailer Disconnected" when I check but keeps popping up with "Trailer Brake Module Fault" on the dash, which I believe is due to not having the proper master cylinder. My current master cylinder only has the one valve/plug on the bottom, towards the front (cruise). I'm trying to hunt down the proper master cylinder that will provide the two valves/plugs. When I searched the part number you provided, that is for hydroboost. Any idea on how to hunt it down for mine, being a gas engine? Thanks
It shouldn't matter, hydroboost or vacuum boosted- RockAuto lists the same MC for both my truck and yours, there's a Raybestos MC391188 on there that should work perfectly. Here's the link: www.rockauto.com/en/moreinfo.php?pk=3284502&cc=1440007&pt=1836&jsn=11064 Cancel Reply
@USAF99 Thanks for the quick response. I was just on there checking out it. It looks like they don't provide the valves with those. I have the one on front. What part would I need to screw into the back? I believe I have the other end of the pigtail in a dummy plug already. Thanks again
I finally got a chance to get after this today. Everything was going well until I realized my hole pattern on my MC was different than yours. Yours are at 9:00 and 3:00. Mine are at 8:00 and 2:00. I can't seem to find one with my hole pattern, the brake control valve and the hydroboost (??) plug on the inside. Any ideas or suggestions? I'm thinking it may be a Dorman M630524 but I don't see the hydroboost plug. Thanks again
I find that these bleed MUCH better by just opening the bleeders at each caliper and running clear plastic into a container. Takes a little time but you get a good bleed with gravity and time. Vacuum bleeders work pretty good too.

Thank You. Going to be tackling this and hydroboost next weekend. Your videos are always so helpful.
Thank you sir. Great video.
Very good instructions. Thanks
Thanks for sharing. Very helpful. - take care man

It's absolutely possible. It's rough, but possible. Thankfully the MC is on flex lines a little ways down so moving it around isn't an issue.

The vaccum refiller is a Pittsburgh Automotive from Harbor Freight, the ratchet tool is a Milwaukee M12 Fuel Series 3/8 ratchet, model number 2557-20.
Good video. Gonna be tackling a 2008 f250 master cylinder thus weekend. Quick question. Do you have to bleed all four brakes or just the fronts?
All four, the two lines go to splitters for front and back.

@@shotpointm28 I want to say it's this one- but double check me. www.rockauto.com/en/moreinfo.php?pk=2065874&cc=1440007&pt=13521&jsn=1118

You didn't have to bench bleed the cylinder?
I find that these bleed MUCH better by just opening the bleeders at each caliper and running clear plastic into a container. Takes a little time but you get a good bleed with gravity and time. Vacuum bleeders work pretty good too.
Did you use forscan to bleed the abs?
You can use Forscan or an Autel, I have done it with either. Just make sure you do it a few times, it's not a "one and done" type deal.
Hey bro, can we get that part number please. Thanks again 🤙
Did you ever find the part number?
@@jacobrising3570 I did.
