No effect at all on brakes
like all diesel engines this also has a vacuum pump for the brakes and since it is older style mercedes, this vacuum is used for central locking mechanism and engine shutof also

Like I wrote above this engine was also made without EGR, only difference is intake, exhhaust, a few linkages and pipes between exhaust and intake

So this throttle plate only function is to allow intake get clogged with soot from EGR

Later I will get the non EGR exhaust manifold and intake to increase efficiency even more and make room for water injection (this EGR intake is also very big and makes engine bay crowded)
