Brake replacement

[meanc]

Good morning everyone. Hope all is well.

New to the site and want to thank everyone that has contributed their troubleshooting/repair experience to guys like me.

Right now I am tackling the rear brakes. I've read a few posts and have 99% of the tools for the job. That 1% happens to be the 15/17mm wrenches.

All I have are standard width and thickness which apparently is a problem.

My question is what dimensions should I grind them to for a proper fit?

Thanks in advance.

Wouldn't it simply be cheaper and easier to buy a metric set? Even just the 15/17mm? (or am I missing something obvious? )

My question is what dimensions should I grind them to for a proper fit?

Is this a trick question?

Maybe I am also missing something.

The standard wrenches are a bit to thick to grasp the nut on account of the flange that's on it. Honestly, I just use pliers and grasp the flange and it works fine.

As Roverman stated, the wrenches in their factory form are too wide because of the flange around the mouth.

A standard wrench needs to be narrowed to fit on the nut. I'm trying to find out just much to grind off so I can have that done. So, when the components arrive I will have everything at hand and ready to go

I just did my brakes about a month ago and was also concerned about the wrenches that I had fitting. In my case the ones that I had worked just fine so no grinding was needed. It might be worthwhile to check yours first as your mileage may vary. It was pretty easy process overall.

Thanks Craig. I guess I'll have to check and see first. Hopefully I'll get lucky.

Finished replacing the rear pads and rotors this morning.

Luckily there was no need to grind the 15mm wrench. It barely fit, but I got it in there.

All in all it took about an hour to complete.

It's always so nice when someone takes time to follow up on a thread. Thanks, and well done.

Here is a list of specific tools and process for doing the rears on the LR3.


#1 T-50 Torx head for the rotor

#2 13mm box end wrench or socket (outside) and 15mm box end wrench (inside) to remove the brake housing from the sliders

#3 15mm 12pt socket to remove the caliper from the hub.

#4 7/16" box end wrench to loosen the bleeder screw.

#5 6" C-clamp to compress the cylinder. (a 3" will also work)


I removed each component in the order listed above and cleaned everything thoroughly (including everything still attached to the axle) with brake cleaner.

#1 Put on the rotor and attached the torx screw.

#2 Put new pads into the brake pad housing and reattached it to the sliders (13mm and 15mm wrenches)

#3 Reattached the caliper. (15mm 12pt bolts)

#4 Bled the lines (7/16" box end wrench)

#5 Put the wheels back on.

#6 Topped off the Brake Fluid reservoir.


Hopefully someone will find this helpful.
