Replacing rear brake pedal Triumph Speed Triple 2006

rnexussix's picture

My  rear brake pedal was bent after it came in contact with asphalt  when I lowsided the bike on a canyon run. You can read about that here: http://www.motohowto.com/content/dreaded-lowside

The old brake lever  was functional, but it was bent in such a way that stuck out a bit too much and it was in general an eye sore. So I decided to replace it. Since I didn't have to do it right away (the bike was ridable), I took my time and waited for a custom search that I configured on e-bay to notify me of a good deal. a couple weeks later I got what I was looking for. Someone put up a brand new rear brake lever for speed triple with "Buy now " option at  $50.00 + Free shipping.  This part is sold by the local Triumph dealer for $80.00 + %10 tax. With almost $40 discount to the MSRP,  I snatched the lever from E-Bay using "Buy Now" and it arrived at my door 4 days later. According to the label on the OEM bag the Triumph part numer is:  T2020129 (Picture below)

First I had to remove the right side "control plate". Right side "control plate" is a part to which  the right  footpeg, brake lever, rear brake light switch are attached too  and which in turn is bolted to the motorccyle's frame by a two hex 6mm bolts.

This is what the  right side control plate's back side looks like when it is detached from the frame (see picture below). Note only a single attachment point for the both ; brake light switch the lever return spring. The new lever has TWO attachment points, one for each spring.

 I disconnected the both springs from the attachment point on the old pedal (picture below)

Then I removed the circlip that keeps in place pin which attaches brake pedal to master cylinder (just lifted the upper lip and slid the circlip off the bolt). See picture below:

With the circlip removed, I removed the clevis pin and disconnect the pedal from the rear brake's master cylinder.

Next I undo the hex bolt that keeps pedal attached to the control plate using 5.5mm hex key (picture below).

With the last bolt out the pedal is separated from it's attachment points and I compare the old (bent) brake pedal to the new one. See picture below - new pedal at the bottom, top is the old one. Also note TWO spring attachment points on the bottom (new) brake lever.

I used blue loctite before I replaced the hex screw that attaches the brake lever to the control plate. A small drop is enough.

Then I replaced the screw and  and attach the the pedal to the master cylinder . Circlip slides right on and clicks in place. Then I reattach both springs, one to it's own attachment point this time. Pic below:

Since the distance for the rear brake light switch spring has changed a little (because of the new attachment point) I readjust the tension by rotating the plastic nut which sets the position of the rear brake light switch. See the black plastic cylinder in the pic below.

With the pedal and the springs attached I test the brake light operation before I remount the control plate back on to the motorcycle (just in case I need to re-adjust the brake light switch position). So I turn on the ignition and press the brake pedal watching the rear brake light. The light is off without any pressure and as soon as I press the brake pedal with my hand the light comes on. Since everything working as it should I proceed to bolt the control plate back to the frame (with a drop of red loctite on each attachment point).

With the control plate bolts in place and torqued to the factory spec. the job is done. Here is what it looks like (picture below).

The whole procedure took about 30 minutes.  Triumph mechanic wanted to charge me $80.00 for the brake pedal replacement. So, let's see ..... $80 labor + $40 I saved on the part = $120 bucks ahead of the game.
