- 'Lo all. I have a 1999 Lincoln Town Car that I'm putting front brakes on. This isn't so hard, in and of itself, but I'd also like to turn the rotors because I have some uneven braking that's typical of mild rotor warpage.
- The problem is, the hub cover has this rubber seal on it, and that seal says "permanent sealed bearing - do not remove". I'm curious how one is supposed to turn the rotors on this vehicle if they can't be taken off? If they can be taken off, I'd like some insight into how that's done without damaging anything.
- I did pull back about 10mm of the rubber seal, unfortunately prior to reading the warning. (wry grin) Some gentle prodding didn't even budge the hub cover, which normally doesn't take a lot of effort to remove. Once I saw the warning, however, I stopped cold and came to the web to see what I could see. (grin)
- Thanks for your time...

With caliper and the bracket removed the rotor just falls off! It may be stuck from rust and DON'T bother turning it as they don't cost that much for a good new one. None come with tons of extra metal anymore and they just warp from heat when thinner. Clean and lube where the rotor contacts hub/bearing as if it's crusty it will behave like a warped rotor. A rubber hammer should do to loosen it up and then gasket scrapers for any rust. Good luck,

- Odd. Typically the rotor is held on by a really big nut secured by a cotter pin, which is under the hub cover, the that says it's a permanent sealed bearing in this instance. Naturally the bearings are in there, too! (grin)
- If there is no such nut on this Town Car, what keeps it together? The caliper can't be holding it on there. Mere friction doesn't seem like it should suffice to hold a front wheel on (naturally the studs are in the rotor and hold the wheel) during normal driving conditions.
- I'm not telling you you're wrong, Tom, and I greatly appreciate your response. I've been working on cars for about twenty-five years, and I've never heard of a front rotor (coasting wheel on this rear-wheel drive car) that's not held on a by a nut/cotter pin.
- So before I just start whacking on it with a rubber hammer, I'd feel better with some explaination of this arrangement. Be as technical as you like ... I've a fair bit of automotive experience, and I'm a software engineer to boot, so I don't believe in "too much information". (wink) Links and/or diagrams would be a real bonus. Or maybe I should just see if Chilton has a manual for this car? (snicker)
- Thanks for your time!...

I don't have much time right now but know that the front wheel bearing is a barrel and sealed unit and the rotor comes off like a brake drum would. Bearing is NOT serviceabe or adjustable. Easy to replace with air tools if needed. They use thread lock on the orig caliper bracket which must be removed to get rotor off.
Again - don't waste your time turning a rotor on this. New ones are too cheap to bother. That's your call.
Hit me at base address if needed, I need to get off this computer right now, Good luck,

- Gosh I am SUCH a retard!! Of course that's how it is!! The rotor is held on by pressure on the studs, when the wheel is on there, and it's the HUB that's held on by the bolt!! (smacks forhead)
- Since I can turn them for $15 for the pair, I don't think I can replace them for that price. I'm sure they'll just warp again (they did the first time), but at least I'll have smooth braking for while. (wink) I'll see about replacing them next pad set ... I'm not one to turn rotors a second time regardless.
- Thanks a million for your patience, Tom.  I sure feel like a n00b...

Tom - I've got a '91 Town Car and I want to replace the front brake pads and rotors. You mentioned that the '99 Town Car rotors just falls off when the caliper and braket are removed. Is this the same on my '91?
Thanks, John

Not sure but 1991 should be the old style. Just two 11/16th bolts and regular wheel bearings. That was a change year for Lincoln so I'm not sure. A quick look will tell.
FYI - I've had great luck with disc pads called "Porcelain" for being real quiet. Just a tad more money for less problems. With a 1991 take a good look at the flex hoses and calipers and consider bleeding them out with good new brake fluid, good luck,

Thanks for the insight and the advice on pads. I've never done brakes before so this should be fun.

You are scaring me!! If you've never done brakes before go one at a time. Parts are asymetrically opposite so you have a reference. Make sure that the caliper hose is in proper position and DON'T let it hang by it while working.
Take most brake fluid out of master cylinder with a new clean turkey baster an mark it for cars only!! - or throw it out!! Hit me at home base if you have troubles or questions - I'm at this silly computer way too much so I'll catch it. Never re use brake fluid. There's a spot for private messages here if you want to leave a phone # or get mine. Take your time, it'll work just fine, Tom
