I've been seeing Tesla owners of the sedans finding some issues of pedal pressure response. (These persons, of course, are driving their vehicles on tracks but have found an issue with the master cylinder).

It seems (for example) the Tesla Model 3 the master cylinder is flexing on the sheet metal/firewall and is reducing the response time of applying pressure to the brakes. After installing an aftermarket brace to the master cylinder they have improved the response time and obtain more solid braking.

I'm bringing this up while the CyberTruck is still not in production to help bring awareness to make sure the master cylinder is adequately mounted to a stiff bracket/backing firewall structure member.

Using the truck, I'm sure most will be hauling heavy loads either cargo or trailers and will want the ultimate braking power/response time available to us for braking.




Here is an example of Tesla Model 3 Master Cylinder movement.

Not an issue for everyday driving including towing. This is about pedal feel and quick response for racing.

Just had a 3 for about a week (loaner). Don't think I ever touched the brake pedal - and I guess I'm glad I didn't!

Give a Like - thanks.
Thanks for bring that up. It is something for their engineers to consider.
