'97 Grand Caravan Brake Question
A while back I posted looking for recommendations for good brake rotors due to my van's warped rotor syndrome. I wound up getting Raybestos PG + rotors and the quiet stop plus pads (ceramic) I also replaced the rear shoes and cylinders, flushed the system & put a combo kit on the rear axles. The van warped the new rotors while using the lightest braking while breaking in the rotors and pads. ( and yes, I use a snap on torque wrench religiously ) The steering wheel now literally wags back and forth when stopping for lights. It just gets worse and worse just like all the other rotors I put on this thing. I know its the fronts because it stops smooth via parking brake. I'm thinking now that the hubs must some how be warped, causing rotors to go all the time. ( I should have resolved the brake issue when it was new, I already noticed warping on the drive home from the dealer with 24 miles on the odometer. By the time I made my first complaint, I was over the 12k mark & the dealer said I was SOL, so I've lived with this prob for 87k now. Any ideas on what to look for ? |

I had my front rotors and pads replaced on my 1996 Caravan about a year and a half ago. I believe that they were warped when I got them. This is how they felt; with light touch they was alot of pulsing which became less as I applied more pressure to the brakes. This pulsing got less and less over the following year or so, as (I'm guessing) the wear caused by the brake pads removed the warp. Carl |

Not sure what to tell you. I have never had an issue with any of my vans
I"ve owned at all even with my wife driving them (as she's quite hard on brakes and driveline) and I've owned 5 of them from an 85 to my current 99 T&C ltd. Do you have allow wheels? If so there may be some layer of corrosion behind them and on the hub. But I've had perfect performance from my brakes (even when I've used the chinese rotors).

I get the feeling its just something with this van as well. The rotors warp
pretty much as soon as you put them on and get progressively worse. Rather than complicate the original post - yes I do have alloys. With the last change, I went as far as using a scotch brite pad on the rim's mating surface. I'm waiting for my magnetic mounting base to arrive so I can do a runout measurement on the front axles & hubs.

If that is the problem, it would have to be solved by replacing whichever of the two front bearing/hub assemblies is bad. If you have access to a dial indicator with a magnetic base, you could take the front wheels off, tighten the lug nuts against the rotors evenly to hold them flat against the hubs, and measure the lateral runout of the rotors. Assuming the rotors themselves are true, any runout would be due to the culprit bearing/hub. Otherwise (if making the measurement is too much trouble), just replace both front hub/bearing assemblies. I feel your pain - back in 1973, I bought my first brand new car - a Mercury Capri with a hot-running German V-6. From day one, it shook on braking, and not just a little bit, and cupped the tires. The Ford dealers were no help. After a year of replacing this and that on the brakes, I finally figured out by process of elimination that the only thing left was the wheel hub. In those days, they used tapered roller bearings, and apparently one of the pressed-in bearing seats was slightly cocked in the hub, either due to an improrperly machined hub or a piece of dirt behind it, because when I finally replaced the hubs, the problem totally disappeared. A lot of frustration, money, and nasty letters to Ford (you think customer service is bad now - it was way worse back then) before I finally fixed it on my own. One last thing to rule out before you replace the bearing/hub assys.: Make sure that there's no rust or dirt between hub abd rotor and rotor and wheel causing things to tilt (doesnt' take much). I know you said the problem was there from day one, but you should at least check. However, I suspect new bearings/hubs will fix it.
