Front Caliper busted off...

14 posts in this topic

The other day my front caliper came off the mount on my '01 426. The mounting bracket lower stud threads were ripped open. Luckily I was only going slow.

Interesting ride back to the truck...:thumbsup:

Any ideas as to where to get this mounting bracket? I don't want to buy a whole new caliper from Yam.

I have not found any aftermarket calipers at all. Are they even available?

I can weld and tap this piece up, but I'd rather not.

Any ideas.

Thanks

Put in a Heli Coil or Time-Sert. Takes ten minutes and is easy to do, if you work slowly cand carefully. Think. :thumbsup:

Pics of the damage? MAybe it can be repaired, amybe not. I agree with not welding it. Chances are that it would warp a bit from uneven heating and bind the puck. E-Bay is your best bet for a reasonably priced replacement.

Thanks, I'll try to post some pics. My description wasn't too good.

The stud didn't get pulled out of the threads, the stud got imacted and blew out through the side so there is a big U shape instead of a hole.

Wleding would not be a bad solution, warping is not an issue if pre-heated correctly. Just more a pain in the butt.

Also, do the aftermarket YZ stainless braid cables follow the stock routing where they do the roller coaster douwn by the hub? I need new lines and There isn't one made for just WRs.

Thanks

Ah, then it is a weld or replace job. Welding really depends on how good the welder is and you need a good one. Any areospace/defense contractor companies hear you?

I used a kit made by ride Engineering that re routes the brake line to the newer style of routing(CR) and it attaches to the lower fork guard with an aluminum clamp. Yes, it is WR specific. I did this several years back so it may not be made any longer.

Just checked

Ride engineering

P/N BL-02012-CL

Alum. clamp required P/N MX-BLC00

Thanks for the part #s.

I'll pick them up at eh same time i think.

There was so much flex in my brake line, that when I had my caliper off and suspended up for bleeding that when brake lever was applied the whole caliper moved about 15 degrees. The lever was always spongy.

When riding without front brakes on difficult single track, I really learned a lot. Made me better i think.

Thanks again for the part #s :eek:

Art,

I did the same thing last year. Considered welding etc, but ended up picking up a caliper off Ebay for $50 and was done with it. Nice and easy. Make sure to look through parts manuals to see the caliper part # is the same as your 06. I got one off a 05 YZ.

:eek:

I just got one off fleabay from an o4 YZ 450. Should fit my 01 WR 426.

Got the whole front brake system including master cyl and lever.

Not bad having spare parts...
