Roadster Brake Vacuum Booster
What Is The Brake Vacuum Booster? I have bad news for you. You aren't as strong as you think you are. You simply can't create enough power in 1 leg to stop a car. You would need a brake pedal 1 metre long for you to be able to apply the same amount of braking force...
Roadster Brake Master Cylinder
The brake master cylinder is what connects the movement of the brake pedal to the brakes of your car. It has the brake fluid reservoir sitting on top and it takes fluid from it and pushes it through 2 pipes into the ABS pump. From there, the pump splits the fluid into...

Hashtag Wheel Bolt Info
What Is The Tightening Torque? According to smart, they should be tightened to 180Nm. However! That has to be a mistake. That's not just tight, that's dangerously tight. Dangerous to the point where they could snap. Here Are The Facts Here are the 2 types of bolt used...
Hashtag Jacking Points
It might not be surprising but the jacking points are underneath the car. Front If you look at the plastic side skirt, you'll see a small indented triangle. This indicates the centre of the jacking point. Instead of a jacking point, it's a jacking seam. Most scissor...

454 Forfour Dash Pod Fitting

453 Forfour Exterior Boot Panel
Remove the internal panel to reveal holes leading to 4 Torx30 screws. I would STRONGLY recommend using a magnetic screwdriver because if you drop any of these and they fall into the boot hatch, you aren't getting them out and they'll rattle. Inside screws......

Open the boot (you don't need a guide for that, right?). Look up into the hand grip and you'll see a Torx20 screw. Remove it. Grab the panel and start pulling all the way around. It's only held in place with 8 clips and 3 pegs. To refit it, just line it up and give it...

Fortwo Alloys On A Roadster
This is a bit of a divisive subject. On 1 side you have people who don't think about it and just fit them. On the other side you have people who staunchly oppose such things because it's either dangerous or blasphemous to degrade your superior Roadster with wheels...
