That rod (bolt) thru the middle that holds ur brake together gets too tight. You can disassemble and clean it or just loosen the nut on the front and watch em snap back to open position

Tswinter1's got the most likely cause of the brake issue--the nuts are too tight to the brake arms. There should be two nuts on the end of the bolt--you'll need two wrenches to adjust them right. Tighten the inner one until you get the slop out of the brake arms, then back it off about a quarter turn. Then, holding it in place, tighten the outer nut against it, locking them together.

You might also try unhooking the springs from the brake arms and bending them upward and away from the brake arms a little to give 'em more pull. Don't go too far, though--they can snap.

Cam bearing is scored due to blockage from debris in the ocv...blockage is preventing vvt control and setting code p1349...dealer recommends replacing engine? help!


if the cam shaft is damaged then the cam shaft will have to be replaced
if the shaft is still serviceable then the bearing shells will need replacing
The problem is the blockage in the oil galleys
To do a good job ( professional) the engine will have to be stripped right down and the oil galleys blown out completely after washing in a solutions tank
You will have to get quotes from engine rebuilding shops as to that cost It will be cheaper if you can pull the motor down yourself and then rebuild using any new parts as required
The valve timer unit may be able to be stripped and cleaned out or new units would be the way to go
OK no knowing what is entailed to do a professional job, the next course of action would to be to price a full motor from a wreckers , preferably one that has rear end damage so that there will be no engine damage. This would entail a swap over of motors. Quicker and within the scope of a mechanically minded person
Next would be a fully rebuilt service exchange motor from an engineering shop ( warranty included) and again it is a remove and rebuild operation. again it would be quicker
don't be fooled into thinking that a oil change or an engine flush will do the trick as it will cost you more in the long run

Sounds like air leaking inside won't pressure up & shoot


It probably needs servicing. Strip gun & clean it may have water inside from compressor and/or may have too much oil inside (may have no oil at all and be seizing up). Clean & check O rings. ( I replace O rings during a service). When rebuilding apply a little Teflon grease to the O rings and smear a little inside the sleeve, do not add oil at this time. Connect to airline and check for correct operation. If all OK add a couple of drops of oil down air intake before starting work as normal.

Laptop processor needs to be replaced


That'll be fun. You are aware of static precautions etc.
I don't think in my years of repairing laptops and PC's I have ever had a faulty processor.
Go online and match the processor to your model laptop. When it arrives strip down to the mother board and remove the heatsink and fan assembly. Release the old processor and fit the new one. Clean the heat sink with isopropanol and affix heatsink compound. Refit heatsink and rebuild your laptop,
Good luck!

My shimano ultegra left shifter is super stiff/hard to push in; what is going on?


Try flushing out the shifter(s) with WD-40, use plenty. The next step will be replacing the shift cables and cable housings.
  • Take the bicycle in an area free of cars and obstacles, such as an open parking lot. Concentration is required when learning to use Ultegra shifters or any other type of bicycle shifter.
  • 2 Mount the bicycle and rest both hands on the proper Ultegra hand control. The left-hand control operates the front derailleur. The right-hand control operates the rear derailleur.
  • 3 Start pedaling, smoothly and evenly. While pedaling is crucial to propelling the bicycle forward, it is also necessary when shifting the derailleur. Pedaling forces the chain to rotate. The chain must rotate before it can transfer to another gear.
  • 4 Push the outside right Shimano Ultegra lever in toward the bicycle. The rear derailleur will shift the chain to a smaller rear gear.
  • 5 Push the inside right Shimano Ultegra lever in toward the bicycle. The rear derailleur will shift the chain to a larger rear gear.
Rear Ultegra Derailleur Control
  • 1 Push the outside left Shimano Ultegra lever in toward the bicycle. The front derailleur will shift the chain to larger front gear.
  • 2 Push the inside left Shimano Ultegra lever in toward the bicycle. The front derailleur will shift the chain to a smaller front gear.
  • 3 Use the front and rear Ultregra hand controls interchangeably. For small changes in gearing, using the rear control. For larger changes, choose the front control. A smaller gear causes the bicycle to travel a shorter distance per pedal stroke but also requires less energy to use. A larger gear requires greater effort but in turn causes the bicycle to travel farther per pedal stroke.

Iv cleaned the brakes and cilinderon my honda civic coupe v reg but the brake is not releasing itself


If ft.brakes are sticking it should be calipers are bad 7 times out of 10...or some may have a ft.
metering valve.....but should be ft calipers sticking...sometimes the hose will go bad but normally it is calipers.....if it is the rear sticking the emergency might be slightly engaged or the rear brake
proportioning valve is bad......jack car up and see which wheels are freezing up by turning the wheel
round and round.see which one is hard to turn....if only one ft wheel is hard to turn change both calipers if hose's look good.if hose's are drycracked change them also because they will go bad internally....although it is normally the calipers.....calipers can be rebuilt ....it has an o-ring around a piston that freezes....but sometimes the piston gets craters inside and you will waste time by trying to rebuild..

I have a problem with de rear brake, if i runing and put de rear brake to stop they closed de pads and not runing again the tire not moving


Hello,

It sounds to me like the Brake Calipers need to be rebuilt due to the sticking problem you have described. You can try bleeding your brakes, but I'm pretty sure it's the calipers.

If you find this information helpful, please vote on this post. Thank You.
