So this week I got my locks fixed (thanks for all the help there guys), as well as my tires all replaced and balanced and all that stuff etc. with an alignment. My X-Type beforehand was experiencing wheel wobble under braking and under acceleration at high speeds, 60-70+. The wobble/vibration from high speeds and acceleration about 60-70 is now gone totally after an alignment, but the braking wheel wobble has remained under moderate to hard braking. Low pressure braking does not produce it. My first guess is warped discs, and my initial research is also pointing me that direction but what do you guys think? Where to start? Any tests to run or giveaways to look for in diagnosis?

Again this is my 2.5L Jaguar X-Type 2002.
Thanks!

 

You need new front rotors -maybe pads too.

 

Rotors only 'warp' in 1 out of a 1000 cases. The remainder is a simple case of pad binder material that's built up on the rotor surface. Any garage can remove it quickly and easily with a rotary abrasive pad.

 

I do need new front brake pads anyway so it's a good idea to get the disc rotors at the same time.

 

Replacing rotors at same time as pads gives a beautiful smooth braking, and with such cheap rotor prices, worth doing.
I have not felt any difference between cheap and expensive rotors, longevity maybe, but i replace them often so i cant say

 

If you enjoy possibly wasting money, go ahead.
