transalp xl650v brake pad pins/pin cover

[Ben Hur]

Hi guys...

so I changed the rear brake pads on the alp today...the pad pin cover (the little cap like screw which takes a slot head screwdriver) was stuck in place...I loosened it with an impact screwdriver no problem and the pad pin unscrewed fine without any problems....However I am mindful that that little pad pin cap could have been a major nightmare if it had been really stuck. it seems to be made of very soft metal which can deform easily the moment you try to force it with a screwdriver etc...

my first question to you guys is this...is there any sort of grease which can use on the threads of the pin pad/pin pad cap to ensure that it will keep such problems at bay in the future and at the same time is safe to use on brakes

second - what sort of threadlock do you use on the caliper bolt holding the bolts in place. could not find this information on the service manual?

Copper ease to stop the cover screw cap seizing in. Never had a seized one when this stuff is used, but I do clean and service my brakes before and after winter, so these bits never have time to seize

Personally I don't use thread lock on the caliper reatining bolt, just the specified torque as per Mr Haynes book.

I tend to use Copaslip on the retaining pin ..... and silicone grease on the cover screw, since silicone apparently repels water. But, as Steve t suggests, regular removal is the best way to prevent seizure !

And don't overtighten it in the first place. It only needs to be nipped up.

Caliper bolts are stretch bolts so should be renewed occasionally. Medium loctite...no grease. Strip your caipers off for a good clean a couple of times a year.
As said silicone grease or coppaslip for the pin cover. Don,t overtighten.

Don't over tighten being the key advise here. Here is a new bolt and one removed from my XR400 caliper. You can see how it has been so over tightened at some point the the bolt has lengthened by a couple of mm and is thinner in the middle.

No no no no
Don't clean the calipers, it lets the rot in. Pump the pistons to their working position then slap everything up with waxoil

Did I ever tell you that I occasionally use waxoil on the bike

One thing that seems to escape people completely is to use a correctly sized screwdriver, or screwdriver bit, when removing the caliper pad pin cover screw. Using too small a screwdriver blade will very easy and quickly chew up the already mentioned soft metal of the pad pin cover screw. Never had a problem myself.

Good point! :respect-001:
And it applies to all sorts of screwed things, too,including "cross-head" (Phillips or Pozi) screws.

The use of the correct bit/tool was drummed into my thick head by an experienced mechanic friend....got a lecture on all things torx hex pozidrive etc...so I appreciate that

Well said on a decent screwdriver for the cap. I find an impact driver bit fits perfectly. As for slapping waxoil all over pistons etc I would not be keen. A thin coat of brake grease perhaps? A hot day in the Alps giving it some down from a col you don,t want anything melting in those brakes. I have 3 bikes over 12 years old and they all have calipers in good condition. They do rot if not cleaned regularly.

Guys...the new forum is already proving itself to be useful!!. having looked at the bolts in the picture I approached my caliper bolts with caution and torqued up as per factory service manual. Indeed one of the bolts just did not tighten up with the torque wrench...suspecting a failure I removed the bolt in question only to see it elongated drastically...its not the torque wrench because its a new calibrated one, so the advice is in fact correct....the caliper mount bolts on the xl650v are stretch bolts and once stretched to the working torque, they will need to be replaced...Thank god I had posted on here, otherwise I MIGHT HAVE JUST CONTINUED TIGHTENING ONLY TO SNAP THE BOLT IN THE CALIPER

new bolts ordered of course....my only question at this point is...how do you thank other users?

Beer at the next get together would my choice but failing that there is a little thumbs up in the top right corner of every post.

 

[Ben Hur]

i agree beer would be best ....however I dont have any thumbs up icon...I have 2 icons - to quote and report the post....is it something I need to switch on?

 

[Boris]

Thy doing a CRTL+F5 to reload the page from source. You may have a cached template and the thumbs up was only added a day or so back.

its there now...dont know what you did....but its there now

Guys
I have just received replacement caliper bolts and I have noticed they have a red substance on some of the threads...do these come with threadlock from the factory...if so do I need to so anything particular like activating the compound before torquing up?

Nope. Just torque them up and job done
