Stovebolt.com Forums The Parking Lot Big Bolts 2 1/2 ton brakes

I am currently working on my 2 1/2 ton chevys brakes trying to get them to stop leaking. They are FR-3 type brakes and one of the brass blocks that splits the line between the two wheel cylinders on the passenger side is cracked. Does anyone know of a place I could get a new one? I havnt been able to find one online and most of the trucks at the junkyard were air brakes.
Is there a trick to making the tapered dowels not stick in the axle flange for next time I have to get to the brakes? I had a hard time getting one of the studs back in and im not sure its coming back out.

MattMck,

Is your wheel bolt pattern 6 on 8.750 or 5/10 on 7.250? Is that broken block in the rear or front?

Ed

They are cast wheels so i guess that would be 5 on 7.250? Its the block in the rear.

Do you mean Daytons?

Ed

Yes, they are Daytons.

Matt, Is this what you need?

Almost, but the one i need has two ports as well as the big hole which are at 90deg to each other.

Can you post a picture of exactly where this fitting is located on your truck. Is it on the front or rear axle?

Mike B

Will this work?

It is the rear axle. That might work, but i think it would be tight around the bleeder valve. That or i would have to route the brake lines different. The old one is like that one but 90 deg between the ports. $70 is a lot for that little thing too
