Yesterday I put new read discs and pads in the CLK (all Brembo parts) . When I got it all together at the end and test drove it the parking foot pedal was on the floor before the parking brake held the car on a slight slope .
Today I went out to try and adjust the knurled adjuster nut inside the rear disc , initially I tried to adjust it be removing one wheel nut and a slim screwdriver . I couldn't get the nut to turn .
I took the rear discs off again and after some faffing around took the knurled adjuster nut out disassembled it and greased it . This got the adjustment working again .
I turned the nut until the rear disc was locked , and then backed off slightly until the disc turned with a very slight rubbing . Did this in both sides .
After a quick footbrake test on my sloping drive , the same thing happened again , foot brake pedal on the floor before the car is just held in place .
All I can think of now is that I may need to adjust the under rear seat cable adjustment nut ? (Job for tomorrow when it has stopped raining )
Before I replaced the rear discs the footbrake was working ok with a few more clicks than the recommended 5 clicks , but it was holding before hitting the floor .
Maybe the new disc is a tiny amount larger inside and this could cause the main cable to need adjustment ?
Any thoughts ?
