Complete MBZ Brake System Service and Repair Resources

Recently, I set out with the goal to provide our customers with all the resources they would need to troubleshoot and repair the brake systems on their own cars. As your favorite Benz ages brake problems will arise and they can sometimes be difficult to diagnose. Since brakes are a safety related system it is also VERY important that any repair work be done properly and with great care.

My Transmission Shifts with a Sudden Jerk or Slips - Can you Help?

This is a cry for help we hear almost daily! I keep plugging away at the advanced transmission troubleshooting manual in my "spare" time.  I am currently working on the section that will cover the critical adjustment procedures to the automatic transmission modulator and the proportional vacuum shift valve (where applicable) and plan to release this before the complete manual is finished. On later model turbo diesel automatics these two valves work in connection with each other and must be working and adjusted properly if you ever hope to get your transmission shifting as it should!  And as I have always said, you will know your transmission is on its game when you drive and don't notice it every time it shifts!

Next to the center rubber differiential mount this is the number 2 reason for rear end sag. It is also a primary cause of rear end wander and adverse tire wear. For optimum performance and handling rubber suspension parts on these old Benz must replaced after 18 - 20 years.

Item: VAC-COMVEK
$43.50

Is your diesel suffering from hard brakes, poor or no engine shut off, climate control problems, door locks malfunction (excluding 126 300SD), or even funky transmission shifting??

This unique kit will allow you to clean, tune up, or rebuild your Bosch IDI diesel fuel injectors on your own and save you big $$$!

TWIN Lower Front Seat Spring Repair and Restoration Kit

For TWO 116, 123 and 126 Chassis Sedans, Coupes or Wagon Seat Bottoms

Item: INT-COM2SEATFIX
$82.50
Twin Lower Front Seat Spring Repair and Restoration Kit

This unique kit is designed to help you repair and restore two broken down front seat bottoms so common in the 116, 123 and 126 chassis Mercedes built from 1973 to 1991. And it can be done without taking the upholstery off the seats! The seat must be removed from the car and placed upside down on a work bench. You work with hand tools to install the included hardware from the underside of the seat frame. Average repair time is 2 hours for one seat. No special tools are required other than a grinder (if you need to cut one or more of the reinforcement springs included).

How do I fix a broken down front seat bottom?

Broken down springs on 116, 123, and 126 chassis front seat bottoms are so common on older Mercedes that Kaia finally convinced me I just had to do something about it! And by something I mean more than just using pool noodles, plywood, blocks of wood, wads of bubble wrap, or heavy dense foam chunks. It use to be that you could find a good right side seat spring and install it in the drivers side. But all these used seats in wrecking yards are drying up and new seat springs are $320+ dollars for one bottom. Every one seems to be asking for a solution. One customer recently wrote to tell me he had to switch his wallet to his other ass cheek to compensate for the sag! Talk about half ass!

SVO WVO Electrical Component Twin Activation Relay Installation Kit

Item: GOP-COMTRWK
$36.50

This twin relay kit will allow you to power two electrical components directly from your cars battery and only come on when you turn on your ignition switch.  You can also control each relay with a switch mounted somewhere inside the car  (not included in this kit.

SVO WVO Heated Fuel Path Coolant Hose Bundle Kit

Required for cold weather DTC dual tank operations.

Item: GOP-COMCHEK
$87.00

If you are doing a Dual Tank VO (vegetable oil) fuel conversion you will invariably want to run coolant hoses to the rear of your car. This can help heat the oil coming out of the VO tank and well as keeping it warm as it travels to the engine compartment. 3/8 inch hose is more than adequate for this purpose. In fact 1/2 coolant hose is not desirable because it adds too much coolant volume to the system - thus taking longer to heat it up.

The best coolant hose for this purpose is actually heavy duty fuel hose.  It is much stronger than coolant hose and holds the heat better due to extra internal braiding. Fuel hose lasts longer too when running coolant through it and that is what we include in this kit

Early 123 Rebuilt Heater Blower Motor with Metal Fan - Core Refund

Item: CCP-123RHB1
$295.00

PLEASE READ CAREFULLY before ordering: It has been very difficult for us to provide our customers with replacement heater blower motor units for the early 1977 to 1980 123 Chassis 240D 300D 300CD and 300TD.  It is fortunate that all the motor brush sizes are the same and even most of the early motors are the same size, but the housings and fan units are another matter. Mercedes had two or three different companies producing the heater boxes and blower motors - and THEY DO NOT INTERCHANGE! Even if you try to order by vin number you might get fooled.

hydraulic suspension ext. seal kit

This seal and gasket kit will solve your problems with any external or internal (into the engine) leaks at the hydraulic pump (location at the front of the cylinder head). If your hydraulic fluid is disappearing from the tank and you can't see any leaks in your rear suspension - then it is possible the shaft seal of your pump is bad and fluid is leaking into your engine oil (and yes, this is not good!). This same pump is used on all Mercedes self-leveling suspension systems from the late 1970's up through 1991. Your pump will need to be removed from your engine in order to install new seals and gaskets. You should have correct fluid (Mercedes type) and a new fluid filter on hand before you begin.
