Could be a brake caliper problem. Does it occur with all brake pedal pressure inputs or just light to medium. |

Yep you are right..if I stomp on the brakes it is not obvious...Before I replaced the Rotors the left front Calliper appeared to be out of alignment as the pad wear was not symmetrical. resulted in the pad wearing and sticking without setting the sensor off. Told it was a design fault but I was never sure. I will take to local brake specialist and have them check this out.

Should I say 190,000 kms, new transmission at 187.000, and only issues were (apart from the Tran) caused by incorrect servicing and crumbs in the ignition! Love my RR and have never regretted my purchase. |

OK, I went through this with one of my Jags but the principles are the same for almost all cars.

Thxs mzplcg. I understand what you are saying (just)! It brings to mind an issue my friend had (also a JAG man) getting the front right wheel off. By the looks of it the mechanics who changed the boot had used a lever. It took some time manipulating the car and almost with the wheel nuts off completely to free the wheel. Could this indicate some distortion I wonder. I will quizz the Brake specialists when I go to see if they can handle all of this testing.

Ok, back to basics ... warped discs are not the only source of judder. As already said, the smallest bit of crudd can prevent the dics sitting flush on the hub. Seizing propshaft joints can cause judder etc etc.

I had occasional judder when driving (not braking) in my TD6. It turned out to be a sticking/seized rear near side calliper. it is quite common on these models. Quite cheap and quick to replace with basic tools. No longer FF owner but still interested. Present car Jaguar XE

Thxs Mikeyjd..this is definitely whilst braking but I am thinking the callipers would be the first to check. I am going next week to a brake guy armed with extra understanding from the replies I have had. Bit beyond my girl power to fix myself! |
