Mercedes benz v series

unless you have all the tools to remove hub and replace bearings they are a nighmare to replace there are videoes on you tube to give an idea but buy the time you pay for tools to do this job it will work out as cheap to get a garage to do it

Buy the Haynes manual for your model,

if its the rear brakes probably the hand break has rusted on or the breakes have seized take wheels off and tap the rear hubs with a hammer not to hard as you could break the drums if this doesent work check behind the hubs and drums to see if there is any movment of the hand break cable if not these have seized or rusted on try spraying wd40 or equivalent into drums to try and release them

if its the front breakes the pads will have to be removed and the front pistons in the calipers will have to be check making sure that they are still in the cylinder runners and haven't poped out which they can if the breakes are very worn down usually to the metal hope this helps ivan

Rear wheels brakes they have to be clean because the brake shoes debris look the drums all so hand brakes at list 3 click before to lock the hand brakes wheels.

you tube has many tutorial vids on brake removal and replacment its not complicated but would take a long time to type what to do

Light Duty Models

1. Raise the vehicle so that the wheel to be worked on is clear of the floor and install jackstands under the vehicle.
   
2. Remove the wheel. Remove the three retaining nuts and remove the brake drum. It may be necessary to back off the brake shoe adjustment in order to remove the brake drum. This is because the drum might be grooved or worn from being in service for an extended period of time.
   
3. Before installing a new brake drum, be sure to remove any protective coating with brake cleaner or a suitable fast-drying degreaser.
   
4. Install the brake drum in the reverse order of removal and adjust the brakes.
   

Heavy Duty

1. Raise the vehicle and install jackstands.
   
2. Remove the wheel. Loosen the rear brake shoe adjustment.
   
3. Remove the rear axle retaining bolts and lockwashers, axle shaft, and gasket.
   
4. Remove the wheel bearing locknut, lockwasher, and adjusting nut.
   
5. Remove the hub and drum assembly from the axle.
   
6. Remove the brake drum-to-hub retaining screws, bolts or bolts and nut. Remove the brake drum from the hub.
   

To install:

1. Place the drum on the hub and attach it to the hub with the attaching nuts and bolts.
   
2. Place the hub and drum assembly on the axle and start the adjusting nut.
   
3. Adjust the wheel bearing nut and install the wheel bearing lockwasher and locknut.
   
4. Install the axle shaft with a new gasket and install the axle retaining bolts and lockwashers.
   
5. Install the wheel and adjust the brake shoes. Remove the jackstands and lower the vehicle.

remover tires, punch pins from caliper remove brake pad sensor assembly from caliper, remove retainer, remove caliper, remove pads, pull off disc and have resurfaced. Install in reverse order. Make sure you replace pad wear sensors.

It will cost more money for the special removal and instllation toll than the job itself. It is apercision bearing and it requires a special tool-remove the drive axle,brake rotor,caliper and e-brake shoes. remove snapring and **** bearing out of hub with tool.

So this is what it takes to replace rear brake rotors on a 2003 Mercedes E320;
1) open the bonnet (hood) of the car and loosen/remove the cap off of the brake fluid resevior.
2) remove outer spring clamp from brake assembly (it clips in to the iner edge of the holes of the caliper).
3)using a 7 MM allen wrench, remove the brake caliper.
4) using 18 MM box wrench, remove the caliper housing assembly off of the wheel hub.
5) using a star wrench, unscrew the rotor locking screw from the rotor
6) squirt some liquid wrench on the rotor hub and knock the rotor with a hammer to work the liquid wrench in.
7) using the same hammer, knock the rotor off the hub.
8) using a metal file, lightly file old residue off of the hub and place the new rotor on the hub.
9) set the hub by screwing in the lug nuts and then screw in the hub locking screw using the star wrench, then remove the lug nuts.
10) reinstall the caliper housing assembly onto the wheel hub using the 18 MM box wrench.
11) push back the brake claiper piston to its home position and install the inner brake pad (the one with the snap clips)
12) insert the outer brake pad in the claper housing assembly.
13) slide on the caliper housing with the inner brake pad in place (over the outer brake pad) and screw in the caliper screw rods using the 7 MM allen wrench
14) on the right wheel brakes, DO NOT FORGET to slide in the brake sensor (the one with the black connector) and connect it to the connector on the caliper housing.
15) be sure to reinsert the spring clamp onto the outer brake assembly to set the assembly squarely onto the wheel (there should be no wiggle in the brake assembly after the spring clamps are installed).
16) finally mount the wheels.
17) you can bleed the brakes at this point to release any trapped air (which is unlikely) but be sure to pump the brakes after starting the car BUT BEFORE MOVING IT to re-preassurize the brake system before driving the car.
17) ONE WEEK LATER - recheck brake assembly to ensure all is okay and brake fluid.

This proposed solution is for a 2003 Mercedes Benz E320 and NOT a 2005 model as stated by the limited option selection provided by FIXYA.com when initially describing the problem.
