Question about Mercedes-Benz 220
Failed warrant of fitness because it needed "equalize rear brakes".. What does this mean, it seems a little ambiguous and the chap only did the speed stop (test) once..hope you can shed some light..thank you..
Because the rear and front brakes have different braking ability because of disc rotor size and or rear drum brakes it is necessary to reduce the braking efficiency of the rear brakes to stop the rear end skidding out on sharp stops, wet roads and inclines . To do this there is a small pressure regulator ( equaliser) that allows some pressure through at partial brakes eventually increasing the pressure available to full brakes .IT may be in the ABS unit if you have one or in the rear hydraulic line under the body. The failure rate of this unit is exceedingly small so I would be checking things like pad/lining thickness and seized caliper pins that are not allowing the caliper to centralise and allow both pads to work on the discs or seized pistons in the wheel cylinders that is not allowing full pressure onto the shoes in the drums

for the 220cdi,it is a 611.961 motor, you have to refill 6.5 liter,included the olilfilter.Whenyou have refill,and after the motor has running,you can check the oil-level in the board-computer.

Which brake line are you talking about?. The metal steel ones,or the rubber ones. Doesn't matter. If you are buying the rubber ones, then just ask for them by year and model of truck.
If you are working with the steel ones, they are either going to be 5/16 or 1/4 depending which line it is. the 5/16 ones are usually attached to the master cylinder or the ABS unit. The fittings sometimes if you don't find the right one have to be re used, in which case you will need to flare the tubing. (Double Flare) Or you can go to the dealer, pay an arm and a leg, but you don't have to flare the tubing, which takes the fun out of the job.

Its probably not a fuse issue as that would affect both sides.
when you replace a blub especially the brake lights it is possible to deform that nice flat panel of metalic strips and if you look carefully it sometimes breaks the plastic pins on which it sits, this causes poor connection to the functional bulb, the soloution is easy, get a small piece of card and fold it over till its about 2-3 mm thick then wedge it behind the panel of strips (top outside corner for brake light) and hey presto the light should work again, top tip use an umbrella and the electric seat to make sure the brake pedal is deppressed to check if alone.

This can not be reset by conventional methods. This must be done through a scan tool. Usually only the dealer scan tool will communicate with the SRS module. If the SRS light is on you have other issues and they must be remedied before the light will go out. There is no way of knowing what the issue is without running codes with the scan tool.
