I not particularly mechanically minded but I can do the basics if needed. Regardless I’ve always relied on the professionals to service the bike. However when I had my tyres changed yesterday the guy pointed out some light surface corrosion that, while not a problem, needed cleaning to prevent future issues.

I wouldn’t normally touch stuff like that but having watched him put everything back together I thought that while out of my comfort zone was manageable. If I had the tools...

I have a set of spanner’s and a reasonable socket set but let’s assume I have nothing.

What tools do I need to strip and reassemble the front brakes on the R1200GS (including fancy torque wrenches which I’ve always wanted because they look cool but I’ve never had the need for one)?

Hi

I removed my rear calliper last week to clean it up for the same reasons as stated in your post. I needed a male 'torx' socket (think it was T30); quite easy, just removed three bolts securing the rear mud guard, and two bolts securing the brake calliper and jiggled it a bit. This was all with bike on the side stand (centre stand would have been better but I'd already started and it was raining outside...)

To remove the brake pads from the calliper, I used a pair of pliers to pull out the 'R' clip and then I used a punch and hammer to tap out the retaining pin. Mine was corroded in (hence the reason for cleaning them up) so it was difficult to get out: WD40 helped. Once the pin and pads were out, I used the wife's toothbrush to give the insides of the callipers a good scrub and a wire brush where I could and scraped out all of the gunk from the wear channels on the pads. Turns out my pads were not very worn at all and just needed a big clean up. Getting the fronts off I assume will be similar if not easier as there's a little more room.

I then used some lovely copper grease on the BACKS of the pads and the retaining pin to keep it all corrosion-free and my handy pot of brake cleaner to ensure the disc and pad faces were clean and grippy. Some people consider copper-grease anywhere near brake pads to be sacrilege; a little goes a long way.

Enjoy.

PS I did use a torque wrench to do the bolts back up. It's a lot of fun. There are some good deals on Amazon and ebay. I have two wrenches: one is smaller and good for torques about 5-25Nm (rear calliper bolts 24Nm) and a larger one that is about 18-24 inches long and good for everything else. Both were relatively inexpensive.
 
Thanks. Have you finished with the toothbrush now or is it available for loan?

Keeping the holes in the discs crud free will help to prevent scoring :rob
 
I am now the owner of a torque wrench and some copper grease. My existing socket set will do the job. I have some torx keys but I need to get some torx that I can stick on the end of the torque wrench.

Halfords didn’t have a Haynes so I’m going to do some Googling unless anyone knows of a Brembo specific guide to doing this job?

I'm so glad this didn't turn into a how to strip and rebuild a caliper thread.

And talking of copper grease - there are people out there who think that's the stuff to lube caliper pistons with before refitting them. I bought a Triumph caliper off ebay which demonstrates this...

No. Loads of info out there. I just wanted to know what tools I needed specifically for working on the GS.

I inherited a torx socket set so my only purchase was a torque wrench.

Like I said. Treated with caution since I wasn’t sure that they were a trusted source of information.

If I believed everything I read from everyone I’d be dead or in prison at this point

Textar make o.e. equipment for Porsche etc,

What you actually said was that you'd treat it "with a pinch of salt", slightly different than "with caution"...

Would you not agree that the two comments have very different connotations? :rolleyes:

Rather than purchase a new Torx set to fit your torque wrench just buy an adaptor; one end fits your wrench, the other your Torx bits. Loads on eBay of every possible combination.
 
Nippy Normans supply Touratech, Wunderlich, Desert Fox and many other makes of accessories.
