67-72 rear disk brakes
Has anyone run steel lines straight to their rear calipers and not used hoses?
I know the calipers need to be able to move a little but I don't believe the hoses are neccessary for the rear, just an additional cost. The steel lines should still give enough to allow the calipers to move. Just my thought. What do you guys think? Has anyone done it this way? |

Re: 67-72 rear disk brakes
the calipers need the room to free float to work right. i would put the hoses on and save the problems later

Re: 67-72 rear disk brakes
Steel lines are run straight to mine, no problems. I checked the movement and it's not much if any at all.

Re: 67-72 rear disk brakes
you still need a rubber hose from frame to axel// if you're looking to save money the brakes aint where to do it

Re: 67-72 rear disk brakes
that small additional cost could possibly save your life and others on the road once that hard line cracks.
Not IF it cracks ... WHEN it cracks. |

Re: 67-72 rear disk brakes
Maybe I didn't understand the question. I don't have rubber lines from the axle ends to the brake calipers. I do however have one rubber hose from the hard line on the frame to the axle housing at the tee.
The hard lines at the calipers do not move. I have double checked that now, I see no problem with my setup. Cost is not an issue on my truck.

Re: 67-72 rear disk brakes
If the calipers have pistons on both sides of the rotor, the calipers can be mounted solid and plumbed with a steel line. The caliper does not need to move as long as the pistons on both sides of the rotor are free to move.

Quite correct, the 4 piston calipers or as efabmen said, the calipers with pistons on both sides are mounted solid and don't require a rubber hose while the single piston calipers have to float and move outward as the pads wear and will in time work harden the steel line and cause failure if there isn't a rubber line there. It is also quite possible that a solid steel line would cause the calipers to "stick" to one side of the rotor or the other and not let the caliper float correctly. |

Re: 67-72 rear disk brakes
I forgot that the rear end in my truck has been changed. I have a 12 bolt but the ends of the housing were replaced with some Ford (or other) setup. The brake calipers are bolted solid, they have two pistons.

Re: 67-72 rear disk brakes
I have the rubber hose from the frame to the axel, there's no doubt it's needed there.
Like Fastom said, I don't think the calipers move/slide enough for a steel linr to cause a problem. My 69 is a 4x4 and I would think there would be less of a chance for something to catch a steel line as there would be for something to catch a hose while off roading which is why I was really considering the steel lines to the calipers. Thanks for all the input Rob |

Re: 67-72 rear disk brakes
1, its $40 or less to do
2 how the f do you hard line the steel into the cal? the call is a banjo bolt that uses the thread os the banjo bolt to clamp the banjo down. the hard line needs to end to a flare, cals dont have a felame flare. so how the hell are you hard lining a cal? |

Re: 67-72 rear disk brakes
I don`t see how one would be more likely to snag than the other.Besides,what do you do about the front?I know it`s already been proven plumbing steel to single piston calipers makes no sense when it comes to pad replacement.But,the movement is the main reason to never consider this.The caliper does float on the sliders and having them freeze on the sliders is the most common cause of premature pad wear,usually leading to rotor replacement.Either the steel line will prevent movement or the steel line will move and fatigue.I believe the caliper will just not move.

Re: 67-72 rear disk brakes
The caddy rear disc brakes were just hard lined from the factory. They just cioled the brake line for movement and vibration. I ran a U bend and solid lines to my rear calipers. There is no problem if done right. The only thing is when you go to do the brakes you have to und the line, so for this reason I will be putting in some braided brake lines.

Re: 67-72 rear disk brakes
Not sure what caliper you are using (pics would be good) but if they are like most I have seen, to change the pads, you have to rotate the caliper out of the way.
Do you want to have to reblead the lines, having to remove them from the caliper, anytime you need to change pads? If the caliper you are using is a fixed style (i.e. pistons on the inner and outer) then a hard line into it will work but servicing will be a pain down the road.

Re: 67-72 rear disk brakes
chevy_mike, your point of having to reblead the lines and having to remove them from the caliper, each time I needed to change pads or even service the rear end or wheel bearings, etc., slipped my mind!!!
I'm going to use hoses! Thanks everyone Rob |

Re: 67-72 rear disk brakes
I put some camaro brakes on mine and I just ran the hard line directly to the caliper. Then I got to thinking and reading, and it really does need a flexable line between the hard line and caliper. I haven't driven mine yet, and it WILL be fixed before I drive it.

Re: 67-72 rear disk brakes
how did you hard line it to the caliper?
