    brake lines affecting wheel alignment???

    I had a alignment done a while ago. I had a to change the calipers in the front because they weren't serviced in a LOOOONG time.

    Anyways upon fixing everything I noticed that when I hit the brakes the car pulled to the left. I though I over-greased the ball joints and some of the grease went into the passenger rotor. Kinda true!!. I cleaned it up, and noticed while driving the car still pulled to the left (highway driving, different lanes). Took the car back to the shop and told the guy to re-check the alingment. He said the alignment was checked (dead on) and the rotated tires and everything, he said that the hydraulic rubber brake lines have failed? Does this seem to make sense?

    Anytime I replace calipers I always replace those rubber brake lines that go with them. IIRC they're pretty inexpensive.

    The way that I have had it explained to me is that the hose gets weak and collapses on itself. (you may want to wait for someone else to confirm this) The fluid is able to go into the caliper to engage the brake, but it has a difficult time returning from the caliper.
    Usually the only way I notice this happening is the brake pads will wear very fast, the car probably did pull to whichever side but I didn't notice.

      either the brake line has failed on one side, or one caliper has seized and is not grabbing at all.

        I bled both calipers and phyically observed the pistons compressing,

        I never changed that ruubber hose, for all I know its prolly original.

        Someon else at work told me that over time the rubber hose collapses from the inside as well

          Do the hoses have a lot of cracking and look/feel soft? Like stated,they can cause problems. Can also be a caliper on its way out.

              Well, they should not be soft. If they are very soft, they can expand and take a percentage of fluid displacement, that the caliper needs. This can cause un even braking to the calipers. In simple terms, cause one caliper to work more than the other, resulting in pull to one side.

                  even new parts can be bad. Ask me how I (or anyone else here) know

                    the lines should be neither really hard or really soft. Bend them around your finger. If you see cracks, change them. Did you clean and re-lube the slide pins? Are the plastic bushings installed on the caliper where the slide pins go? Are the brake pads properly installed so they don't fetch up? Are any of the steel lines smashed? You don't have an alignment problem, you have a brake problem. Either something is grabbing when it should not, or its not grabbing when it should.

                      Before replacing anything, I would re-bleed the passenger's side just to make sure.

                      When my 89s started to pull left upon braking the drivers caliper was sticking. Got on the freeway for a ten min. ride. There was ever so slight of a pull to the left there also. Then getting off at my home exit I saw some smoke coming out of the drives side wheel well. Just being one block away I drove home into my driveway. SHAKING I pop the hood to see smoke and flames coming up from behind the rotor. The plastic dust shield was on fire. Watering can put it out quickly. I was picturing the whole thing going up in flames right after getting the 557 running in there. The poor car still doesn't have a dust shield there today.

                        Are the slide pins the two bolts that hold the caliper to the control arms? Don't remember if I lubed them.
                        The pads are indeeed attached right.
                        Plastic bushings???? You mean rubber?

                            maybe they are rubber. been a while since I fooled with them. I haven't done a brake job with those type calipers in several years. yes, the slide pins are the bolts that hold the caliper in. They need to be lightly greased on the end where it goes into the bushing. use disc brake grease, and not much of it.

                              there's no bushings on my 88 or 82 on the slide pins. There's no room. (yes, the slide pins are the longish bolts that fit through the hole in the outer pads)
                              I just dab some axle grease on those when I change the pads.
