I'm about to go to wheel brakes on my Rockwells and plan on using F550 calipers. Will an F550 m/c work with my Chevy shit, and if it won't what will work that can push enough fluid for these big ass calipers?
Que? Habla ingles? You've got Rockwells under a Chevy and you're putting F550 calipers and MC on it...what's Chevy in this equation specific to the brakes. The brake pedal? Booster?DriveTime said:I'm about to go to wheel brakes on my Rockwells and plan on using F550 calipers.

I've been using pinion brakes for a while, and they are what I'm trying to avoid. My question was if an F550 MC would bolt up to my Chevy booster. I don't have access to one of these, and don't have any pics or measurements to go off of, so I don't know if the bolt pattern of the MC matches the booster. And if it doesn't, what MC does match that will work with these calipers.dieselcruiserhead said:a good one is a hydroboost/master setup from a M series (Astro/Safari) van. 1" bore MC if I remember correctly. Hydroboost just ROCKs also, way better than 4 wheel steering. You might need it with the rockwells. The proffitts cruisers guys all run rockwells with toy driveline disks that stop very well. Might be worth a shot IMO if your braking is not very good.
Sorry, lost track of this thread...'96 F450 used a ACDelco #18M484 which looks to be 15/16" bore by my sources. That doesn't necessarily mean that it's gospel though, and it does seem a little small. Something to keep in mind though is that I don't know what the stroke is, so a small bore is capable of generating a higher pressure, while the volume issue can be adjusted up to a point with stroke as opposed to bore. That really comes down to the power booster and pedal ratio.jgarden1 said:Apogee, do you know if all vehicles are now using these quick take up mc? It seems to make good sense, so if not all vehicles are using them, I guess I am wondering why not?
Also are you sure the -96 F450 (I think they were known as the F-Superduty) used a 15/16 m/c. That seems mighty small for those big vehicles. I would have guessed something like 1 5/16?
