Hi, trying to figure out a new issue with my lr3. 132k on the clock.

It’s developed a wobble while breaking, but only around 50mph and only for the very first second or so and then it soothes out. It doesn’t feel like the rotors as it isn’t constant.

Any ideas?
Thanks

It's called judder. At least that's what the Brits call it. Your front rotors are warped. Check your wheel bearings for any looseness. Rover says it's caused by pads that are too hard. They even had pads they called judder pads. But they only wanted you to use them if the truck had the judder. Probably cause they are softer and will wear faster? But now I think they just offer one brake pad.

I see it all the time when someone slaps cheap pads. The rotors are fucked when the pads are worn out. That's just the way it is. Then the super hard pads just make it worse.

Juke is right about the rotor. I said Rovers rotors cant deal with the hard pad. If you buy a good quality after market pad and rotor combo, you should do better.

My favorite combo is Genuine pads and aftermarket rotors. I don't have strong opinions on rotors, but I do on pads depending on the vehicle.

I had a pair that warped earlier and received a warranty replacement, which happens to be the current issue. I had the old ones turned and put on new pads. Wobble gone. I will run these until they warp and then have the other set turned and put on.

One thing I noticed is that the brakes were fine until I started towing my new boat, about 6500lbs. Will see how long these rotors last.

Ok, so new pads, turned rotors and still has the wobble.

Can bad lower a-arm bushings cause this? the whole steering feels a bit loose.

There was a bulletin that had a bunch of steps to track them down. The thing is gone now I think and it had us spending a shit ton of money on strange shit like weighted steering wheels. The bushings got replaced if loose, so yes they agrivate it. But I drive a lot of trucks that have the clunk from the lower arms but don't do this.
Hopefully Jymmie will chime in here but I think the next thing Rover engineers would have you doing is getting run out readings from both sides of both rotors. Also run out readings from the face of the hub and bearing flange. Looseness in the front bearings needs to be checked. I would shake down the back of the truck as well. Look for loose wheel bearings and upper arm bushings.
