BMW E91 335i 2007 Brake Judder / Vibration Diagnosis & Fix

In this video we diagnose and fix a brake judder / vibration on my 2007 BMW E91 335i with 254,000 miles.
This BMW 335i has had a terrible brake judder / vibration for several thousand miles. This happens when braking moderately from 70mph. It gets progressively worse until the speed drops to around 50mph and then goes away. It also gets progressively worse, the more you use the brakes and the more they heat up.

Interesting video, thank you. 12:34 - We usually screw the wheel bolts on with spacers to be 100% sure the disc is tight against the hub. There the disc is kept in place only by the little "safety" disc retaining screw. It's not enough.

Hi, That's a good tip and something I hadn't thought about previously. Thank You :-)

Did the juddering stay away long term? I replaced my rear brakes and it was spot on for a while but came back after a few months. Between 50-60 like you have described although not felt through the steering wheel.

My 2012 e93 has same issue with hard braking over 60mph.

[@djwwautodiagnostics]

Hi, Yes almost certainly caused by warped discs. Does it get worse, the hotter the brakes get?

[@davyvandeven5350]

Isnt that one of the things that bmw had "build" in there cars to make people come more often back for new brakes and pad by the bmw dealer? Like plastic crap everywhere on the cars

[@carolnagy6180]

You should’ve checked the hub as well

[@djwwautodiagnostics]

Hi, the hub / wheel bearing was checked and was 100% smooth with no play or unwanted movement. I have a video coming soon for replacing the wheel bearing on the rear wheel 😀

Just a delay in pressure in the calipers thats makes uneven were of rotors and pads? After the diesel scandal ,my trust of german cars is not that high anymore ,doubt them more than otter cars

[@Mattsts4]

Why skimp on brakes and pads?😮 always buy top quality breaks.

This is definitely not skimping on cheap brakes. Comline are a premium coated product and have performed superbly since installation. Some of the best brakes I've had for a long time. I've had Mintex and Pagid in the past on this car and neither have been fantastic if I'm honest. Would definitely use Comline brake products again and would recommend them 100%.
