The problem was that I sensed a longer travel on the brake pedal, but appears to be quite normal. So, the problem did not exist in the first place.

 

I did a similar upgrade on my C280. I upgraded the fronts to SRT diska and calipers. It all works well, but the long initial brake pedal travel is unnerving. I have investigated upgrading the master cylinder, but Centric seems to think they use different pushrod heights, and are thus incompatable. I have spent time to determine if this is true, but without success. I do know when I upgraded the brakes on my 190E to 500E brakes, I upgraded the master cylinder to the 500E at the same time. I did not have any pedal feel issues at that time. In the reading I have done, it is indicated when you increase the piston size in the front brakes you do need to increase the size of the M/C to maintain the brake feel. Let me see if I can determine if the C280 booster and the C43 booster are the same. If they are, I can upgrade the M/C. If I do, and see an improvement, I'll post the results here.

 

Has anyone been able to remove some travel in the pedal before you start to feel some bite? It feels like nothing nothing nothing brake BRAKE. Not very confidence inspiring. They're hard to modulate. There's not much feel.

 

The short answer is no, the longer answer is it is still being looked into.

 

Have we tried another brake booster?
