VF700F front brakes locked then clutch is not disengaging when put into gear

The front brake calipers slowiy locked after stopping really hard at a light. As I was driving about 35 mile per hour when the lockup began. After trying to get the bike to a safe spot the bike started to lose torque (no spinning of tires etc with locked front calipers). Once I released the pressure by opening the brake bleed screw I was able to move the bike by pushing. Now I can put the bike in first gear with no clutch handle engaged and the bike doesn't spin wheel. I am wondering if this could be the clutch plates or a stuck slave cylinder piston. I am about to check the slave piston, but in the meantime I would see if anyone might have an idea, based on scenario. Also I can turn the back wheel by hand while the bike is not running and in gear. When I engage the clutch it turns more freely.

Thanks for any help..

 

Update, I just removed the clutch slave cylinder and it is working as expected. The slave cylinder piston is not leaking and moves in and out as expected. I took note that the bike starts when clutch is depressed and doesn't engage to build pressure or cause engine to stall. I tried all gears while bike was on service stand, there was no drag on the engine as I went through the gears. When reving the bike he tire spins as it picks momentum. I removed the slave master cylinder and the bike started while in gear, I pressed the clutch switch. So it seems that the bike is staying with a clutch pressed state. When putting the bike in gear the transmission does give the normal clunk as going into first gear. Looks like I am about to have some cool fun..

Advice is needed on what I should look at first by this explanation.

 

Okay update. I have been researching in the Honda manual and it seems that what is happening is friction plate issue, pressure plate, or release bearing. I will start with clutch friction disc since the symptom is that of slipping plates, looks like I might have worned down the already worn fraction plates. O well I ordered a set of EBC Friction plates from EBAY I should have them (set of 7) either Monday or wednesday of next week.

Still looking fro any advice on this issue. Sanity checks are always good.

 

I have been talking to myself in this forum, and yes the conversation has been pretty good so far.. We don't disagree and all my ideas are the best .

 

Well just to butt into your private conversation with yourself...is the problem with your front brake or clutch?

 

Welcome . It is with both the front brake caliper sticking and the clutch. The clutch was working fine until the brakes locked while driving. I have been reading about the stuck caliper on this site and it seems that the pressure is not being released from the caliper. I will take apart and clean the front brake master cylinder making sure the small return hole is cleaned. I just ordered clutch friction plate kits and will have them here Tuesday.

I am still interested in anyone else view based on the information given.

Thanks.

Kind Regards.

 

Sounds like your doing the right thing with your clutch. I would suggest that if your rebuilding the brake master
that you go all out and do the calipers to , cheap and easy to do. My l/f caliper seized up so as a precaution I
did the master and calipers together. Glad I did, you should have seen the crap that came out of everything.

awesome, Garry thanks for the input. I will order front brake caliper kit for left and right today.

 

Update: Received the seven EBC friction plates from a reseller on the Internet $45.00 and free shipping. In removing the old friction plates, it was obvious why the clutch was not engaging. The material on the surface was worn on all the plates. Also the oil was pretty dirty. I cleaned the clutch basket parts and installed new soaked friction plates (2 Hour soaking for feel good). Just cleaned and dampened plates with oil. Put everything back together and now the rear doesn't move by hand when I spin (Good Thing). I now have an issue putting the clutch cover on, found that when I took off the clutch cover the starter idle gear shaft stayed in the clutch cover and I did not take it from there and put it back so the idle gear could stay in place. Well while removing the clutch basket center bolt the gears turned and the starter idle gear moved with no center pivot point. So now to do it right I will remove the Idle starter clutch to recenter the starter idle gear. First clutch job so learning good things for future (inspect and think as I move along). But now it looks good for the original problem of course maybe until I get on the road. I will rebuild the calipers and clean the pressure holes in the brakes master cylinder.
