Here is a loose translation: (hopefully FM would like to rework it or I can do it for him with my limited french schooling and with the help of Microsoft Word [:)]).
Greetings, today I changed the pads and rotors on my E230 (W210) also I have full with photographs for in to make profit all the world. This is valid also for other Mercedes with clamp of the same type!
Initially immobilize the car! then loosen the bolts on the wheels then put the car on jack stands, or better like me a bridge! completely bolts of wheels and deposit the nose gear wheels.
Start by removing the spring of the clamp floating with means of a screwdriver without forcing of too.
Then as you can notice it it is impossible to leave the brake pads without dismounting the clamp. Above all, push back the brake pad using a screwdriver by using the lever on plate to push back the piston of brake slightly. Then deposit them attaching bolts of the clamp with a key of 19 with tube or other if at you it is not of 19! If that forces a little it is normal: of origin there is Freinfilet on the bolt thread for empecher which they loosen in rolling, will thus be necessary to give some to rests!
below one should see these 2 bolts:
caution! once that you removed the 2 nuts you must support the clamp if not you are likely to botch the flexible device of brakes if the weight of the clamp put in tension the flexible device. To avoid having with to hold during lead you can hang it by means of a wire of metal coat rack to the spring of the suspension thus evitant to damage the flexible device and leaving you your finally free hand!
Like this:
Now that us quiet one summons can start with to unscrew the small screw which retain the disc with the hub of wheel by means of one Alen key by retaining the disc of the other hand (perso I have to use a key has tube like extension cable to gear down the exerted force). like this:
Then your disc "being stuck" by time for the hub it is necessary to pass by the method conan the barbarian! In all way it disc then died not of remors! one will type above with a large hammer! but before one takes care to give a bolt of wheel on that and of to screw up with the hand a little so that it takes on the hub, which will permettera to prevent that the disc flies when you type above (and to take it in full pear!). Like this:
After having removed the disc, pass a blow of brush metal on the hub to remove the oxidation, like that:
a then little oil on the hub, very little just for to avoid a future Re oxidation:
personally I just soaked my finger in oil and spread out that over the hub and its flask as on the image if above.
Then one turns over on our caliper whom one suspended has a wire, one starts by disconnecting his catch the sensor of wear like this:
now that the sensor of wear is disconnected one will be able to leave the old worn pads. and then to leave the remainder the sensor wear the old worn pads like so below:
as that you will be able to rest that on your new plates.
Then we will clean the parts or the pads must slide in order to facilitate their displacement and with this intention one will leave the cage the etrier who is just threaded on 2 let us tetons chrome which is screwed on the body clamp but one does not require to unscrew them considering that leaves without that!
on photograph I designe of the finger the hole or engages the famous ones tetons.
Then pass the parts or slide the pads has the metal brush like this:
Then one makes of same on the parts that there is on the clamp:
then one takes an old brake pad (do not do it directly on the piston if not you go the déteriorer)and by means of a greenhouse joint one return the piston in the etrier like this:
Attention on the level of brake fluid in the bottle, with the need to withdraw some with means of a syringe or a pear bus when one compresses a piston the level go up in the bottle!
If as me you make your levels regularly, I have to withdraw a little liquid if not overflow guaranteed and do not forget the brake fluid botch painting!
Then one the cage of clamp gives to its place:
Then I council to put a small sandpaper blow on the field of the plate to have a less direct attack and to avoid the squealings:
One replaces then the capteurd' wear on the new plates like this:
This being made we will clean the threading of the 2 attaching bolts of the clamp using a metal brush (me I was not caught the tete I have used a rotary metal brush)
Remain more than has to pose the discs nine without forgetting to screw up the small screw with the Alen key:
One sets up the plates in the clamp (attention the springs on dimensioned of one of the plates must return correctly in the hollow medium of piston of the clamp) then one puts freinfilet on the bolts of étrié that one cleaned
précédement (attention a drop is enough if not later impossible of desserer!) :
After that one ressere these bolts with the couple using a torque wrench (couple of 115) and one replugs in his catch the sensor of wear of the plates of brakes. one can see the wire which remained on the spring of suspension that one will not have to forget to remove!
To finish we position back the spring (it is not easy but with patience...one arrives there!) and work it veiled is nikel!
Then you do the other with dimensions and finally you go up your wheels, rest convey on the ground will resserez your bolts of wheels and finally attention very important : to pump on the footbrake pedal several times before moving the car if not your 1ere braking will be finished at the hospital because the pistons are not against the plates and celleci must be well in place! controlez your level of brake fluid and made the supplement with the need.
Then small precaution, your brakes are new also it will be necessary to grind your brakes then in one the 1st time avoid the brake applications violent or brakings forts. Then little by little roll as usual quietly during 200/300 km after your brakes will be ground and veiled finished!
Not being pros of mechanics I spent 2 hours to do all that (the 2 front discs!) by counting time to find the tools (it is longest !) and to take the installation for the photographs that my small wife travelled by bus Nico you believe when same step that I would touch my beautiful very new numerical apparatus with hands in this state?
Linear Mode
