Hello dear MTler, My M6 E63 causes me grief after the installation of a Brembo GT brake system for 14 days. The brake pedal can always be pushed through before the braking effect starts. After the installation it was at about 1/4tel and 500 Km then 3/4tel until braking effect – but then extremely good, without reducing the brake pressure during the braking process. After the installation of the Brembo was aired 4 times with different methods. (1/4tel pedal path) I should then once a bissc This means that the main brake cylinder (Brembo) is changed – although the characteristic of the long pedal path could not be closed for a defective main BZ. Even with several “pumps” the pedal path does not change – so it is no longer possible to build up pressure. The brake power amplifier works perfectly, in the FS no error message. As expected after the installation and 6 I have used the dot 5.1 from Motul – that is, the brake fluid preferred by Brembo. I don’t know any more and have made the suggestion to change the hydro aggregate (2,900 €) – but that seems very unlikely – because it is “only” a distributor – if this would have been broken I would probably have rather different braking effects on the wheels. Or does the part have a brake fluid memory? Does someone of such a flaw have In various forums this topic is often dealt with – but mostly without a result being posted. Most people think – it is due to an air intake – which is confirmed occasionally. So far 15 liters of brake fluid have been sucked through, pressed through (2bar), pumped through (with the brake pedal) sometimes with no ignition, running motor. It would be best for me if one said: this is the error – but I am also grateful for every solution LG Rol and
