Honda 400ex - Rear Brake Issues

Recommended Posts

i thought i had bent my back disk brake because the pads are making a grinding sound every quarter turn and the caliper was wobbleing so i took it off to replace it and it was not bent ..........could i had bent the actual caliper or was it knocked out of place ?.......are either of these possible if so witch is more likly?

Check the caliper mount though i doubt it. It might be the brake rotor or hub mount itself. Its not hard to replace the rotor or hub.

Also I have a big problem with mud caking up inside the caliper. Make sure the caliper is clean and the slide pins are gunk free.

If the noise doesnt bother you leave it..

I`d check your Rotor first !! Calipers are hard to bend or break

i replaced the rotor and pads and cleaned the caliper def helped with some but not all the noise ....as far as my caliper wobbling i tightened the bolt that holds the lil mount to the caliper and with the new rotor and pads everything seems the roll nicely.....but decided to roll the quad while the caliper was off and there is still a noise ....... so the issue must be worn out or blown axle bearing i'm assuming ?

Its possible its the carrier bearings making the noise. Did you verify that the rotor hub is true?? If the rotor hub is bent the rotor will bend when its bolted onto it. How bad is the noise?

Last thing would be to remove the rear axle and spin each carrier bearing individually by hand to see if they are making the noise. If no avail post a video of the source of the noise

hey thanks for the help after finally getting around to fixing the problem it ended up being a blown bearing in the carrier it had a lone star dual bearing carrier in it witch i was not aware of because i bought it used ...3 of the 4 bearings were in ruff shape but still solid i believe thats why there was no play in the rear end ....there was also a crack in the carrier i imagine from the previous owner beating the bearings in so i have ordered an entire carrier assembly just waiting on it once i install it make sure 100% everything's good to go ill let you guys know thanks again for the help

      recently picked up some project bikes off CL for cheap.  got a honda fourtrax (the ancient 4x4 kind with the straight axle in the front as well as the rear and a back-up kick-start)  plastics are crap, but my goal is to get running like a champ and patch the plastics up and sell to one of my many friends that want a reliable 4x4 for dirt cheap and doesnt care what it looks like.
      so the former owner says it needs carb rebuilt, but its sat for 3+ years since so who knows.  things I see:  carb is missing (he gave me a box of parts along with the bike), engine turns over and feels good with kick-start, brakes need work, battery missing (That always puts me off, cause then I know most likely someone's been tampering with the electrical.

      I know...I feel stupid for asking.  I find it impossible to use the thumb throttle with my thumb when I have the bars turned full right. I have to reach across the top and grab the throttle from the front with my fingers. It isn't very smooth and I can't help but think that there must be a technique, mod or adjustment for this. How do I get past this?

      I cannot get this drum off, I already have another drum and backplate on order because I've ruined this one trying to get it off. Completely rusted to splines. I cant fit any hub or wheel puller known to mankind onto these lug studs to try and pull it off, I'm really running out of ideas.

      I was riding my 400ex one day and when i shut it off to put it in the garage i tried to start it put again to drive it into the garge and it wouldnt start.I put a compression tester on it and its like 30 psi with out throttle and 0 psi WITH THROTTLE.
      when i put my finger over the hole it fell likes its pulling my finger in more then its pushing it out 
       
      Has good spark.When i took it into the shop the said it had 1oz of oil in it and a tiny pit of metal shaving(TINY BIT LIKE 30 flakes)
      When i try to pull start (push start/roll start) it made a not normal sound  and wouldnt stay running.
      If my bottom end is blow why would it still turn over fine,
      Are my valves siezed or not working properly 
      or is my timing off causeing valves to not open in correct order with fire 
      PLEASE HELP all help is appreciated

      I loosened the allen bolts on the carrier and when I went to put my driver in the alot to pull back and tighten the chain, I noticed the holes were facing the front of the bike. I tried to slide a driver in and tighten the chain but the thing would not budge. I nearly ripped the tip off the driver in the slot. Any suggestions?

      Am i better off to just replace the bearings or buy the whole carrier?

      The title is for attention. I’m prepping my cylinder head off of an unknown year 400ex to install on my quad. And I’m examining it and there’s literally a Jewish start( Star of David) protruding from the metal on the camshaft side of the head. It’s not imprinted or etched/ engraved. It’s coming out of the metal. DOES ANYONE HAVE INFORMATION ON WHY ITS THERE??? I’ve attached a picture
