The British Guide to Replacing Brakes
By Louis
A half informative, half humorous guide on fixing your very own brake discs rotors and pads.

Disclaimer: Although this game does a pretty good job of covering many of the aspects of vehicle repair and maintenance, there are many more things that need to be considered in real life. Please do not attempt to follow this guide for that purpose as it may result in possible personal injury. Always seek specific professional advice and guidance for the vehicle you intend to work on. Thank you.

Safety and prep
Ensure the vehicle is safely supported on Jack Stands.


Remove the wheel trims.



Prep your ugga dugga, or long ratchet - wheel nuts use the 19mm socket and are usually pretty tight.



Loosen the wheel nuts



Realise the gun was on Tighten.
Ensure your gun is set to loosen. Loosen the wheel nuts.



Remove the wheel and slide it under the car to keep it warm. Probably also something to do with safety, but it's already hovering.
Identifying parts
We're going to take a look at the brake assembly, identify a few key parts and then start with the actual job.


The solid disc is known as the brake disc. Pretty self explanatory.
On the left is the caliper and pads. The caliper is essentially a large piston which pushes these abrasive pads into the disc to slow the car, this will also eat away at the disc and pads over time.



Behind the caliper is the caliper mounting bracket. This holds the caliper to the wheel hub and contains hardware which keeps the pads from being in constant contact with the discs.

We'll be replacing all of these parts, as well as the hardware.
Uninstalling parts
The first part to come off is the caliper. Find the slide pins on the rear of the caliper and unscrew them. Here, it's a 12mm upper pin and 16mm lower pin.


We'll crack off the bottom pin first and take the top one out first. This is because if we completely remove the bottom pin then try to take the top one out, the clam shell of the caliper will open.
This can be useful if you just need to change the pads.

Of course, this doesn't really happen in game. Do it how you want to.

Put the 16mm on your ratchet.


Remove the 16mm from your ribcage and put it on the ratchet.


With the bottom slide pin loosened, we'll remove the top pin.


Use the 12mm on your ratchet and remove the top pin.
When loosening bolts, make sure you don't put too much power into it or you'll end up punching metal somewhere.


With the top pin removed, remove the bottom pin, caliper and the brake pads.


Next, remove the caliper mounting bracket. Here, it uses 2 14mm bolts. Crack them off with your ratchet and loosen them by hand.


When the mounting bracket is off, you can usually just take off the brake disc. Sometimes these will have retaining screws.
Parts to order
Literally unplayable


For brakes, you should always replace them in pairs, specifically fronts or backs. Not left or right, but I've seen some stupid things before.

You will need:
  • 2x Brake rotors
  • 4x Brake pads
  • 4x Brake pad shims
  • 4x Brake hardware type 1
  • 4x Brake hardware type 2
  • (OPTIONAL) Slide pin (Large)
  • (OPTIONAL) Slide pin (Small)

And that's everything. Brakes are pretty simple.
Lets get this put back together, grab a beer and call it a day.
Installing parts
The easiest and first parts to replace are the hardware pieces... which is the biggest f***ing lie you'll ever be told.

With each shim, place them on the back of the pads.



The brake hardware is slightly more confusing.
For the right pad, hardware type 1 is on top and hardware type 2 is on the bottom, but for the left pad, it's the opposite way around. This is true to both sides, passenger and driver.
Rear brakes only use one hardware type.


Side note: if the devs ever add copper grease, you should apply it to places with metal on metal contact.
Don't put this on the front of the pads because, as you can imagine, greasing the thing that stops your 2-ton metal death-box is really stupid.


After you've finished installing the shims and new hardware, replace the pads into the mounting bracket. Then simply reverse the order you've taken the system apart.

First place the brake disc on the hub. Then the caliper mounting bracket should be installed with the 2 14mm bolts.

Next install the caliper with the 16mm and 12mm slide pins. Some people would say you need to torque these to 82nm. I say 3 ugga-duggas should do it.


If you actually want to know torque specs, use the guide below.

Finally, install the wheel and trim.


Now do the other side :)
