tokabochi 9 Posted August 5, 2011 Share Posted August 5, 2011 OK in the floods we had last week my friend is actually away and his car was in his garage. It seems that the water did NOT get into the exhaust, just about under that level, and that the engine seems to be ok as they can start the car no worries. But apparently one back wheel 'won't turn', so it has been hauled off to the overcrowded car repair company. Any ideas on what that damage might be? Just needs a bit of a clean and dry perhaps, or something more. Link to post Share on other sites
joshnii 2 Posted August 5, 2011 Share Posted August 5, 2011 Car companies busy in Niigata right now with a backlog of flooded or part-flooded cars. Link to post Share on other sites
Jynxx 4 Posted August 5, 2011 Share Posted August 5, 2011 If it is the front , Wheel bearing is locked up. just needs wacking and grease packed in. If rear is drum brake. it´s probably jammed a bit. Take it off and put it back in, sort of job. (Released the hand brake but it´s still stuck or something, is it?) That would be my guess Link to post Share on other sites
snowdude 44 Posted August 5, 2011 Share Posted August 5, 2011 Yep like Jynxx said, most likely brake is jammed on if the car has rear drum brakes! Link to post Share on other sites
tokabochi 9 Posted August 5, 2011 Author Share Posted August 5, 2011 Thats encouraging. Have asked for an estimate before doing any work and should have that tomorrow. Hopefully it will be a cheap checkup and clean kind of job. Link to post Share on other sites

Goosie 0 Posted August 6, 2011 Share Posted August 6, 2011 really are there still drum brakes used on cars? It's either double ventilated discs front and single ventilated back or just disc back. Link to post Share on other sites

snowdude 44 Posted August 6, 2011 Share Posted August 6, 2011 My wifes Diahatsu has drum brakes, actually most of the K- cars still have drum breaks new and old. Link to post Share on other sites

Go Native 70 Posted August 6, 2011 Share Posted August 6, 2011 K-cars are light and have really small engines meaning not much power. No real need to have disk breaks. Link to post Share on other sites

panhead_pete 27 Posted August 7, 2011 Share Posted August 7, 2011 If its the rear its quite possibly the hand brake that is stuck on. Link to post Share on other sites
HighlyTrainedNovaTeacher 2 Posted August 7, 2011 Share Posted August 7, 2011 I don't understand cars at all, but just out of interest why would water make the brake stick? Link to post Share on other sites
Jynxx 4 Posted August 8, 2011 Share Posted August 8, 2011 Cause and effect. Nothing else had contact or affected the car since it was garaged. When the hand brake is on, the brake pads are pressed onto the drums. This surface contact is rather large and the water rusts the surface of the drums (and some iron that came off the drum and impregnated onto the brake pads) and bonds. It increases the friction the of the surfaces on all parts inside the drums. That´s what I leant, but my personal theory is, its a bit like sharpening a knife on a whet stone. the muddy thing makes the smooth surface of metal and the stone stick creating a vaccume. If I leave that to dry, it will not only rust but the mud will act like glue. Link to post Share on other sites
tokabochi 9 Posted August 9, 2011 Author Share Posted August 9, 2011 Not sure the details but happily it wasn't anything major. They are charging 20,000 yen for picking up the car, doing the tests and doing something to that back wheel. Sounds like it could have been much worse so I think he'll be pretty relieved.

If I leave that to dry, it will not only rust but the mud will act like glue. That's pretty much correct - the pads will "bond" to the inside of the drum by the rust. I've seen this happen a lot in older trucks with rear drum brakes after deep fording. The easy cure is parking the vehicle with the wheels blocked and leave the parking brake off so the pads aren't tight against the drum. That way they can dry out without the pads and drums rusting together. What Pete said can happen too, where the parking brake cable rusts inside its sheath/housing and won't release the brake mechanism. Good to hear everything was worked out for not a whole lot of money! Link to post Share on other sites

Even some current "all disc" cars still use small drum brakes as parking brakes hidden inside the rear brake rotor hats, so you can still have this happening in a 4-wheel disc brake vehicle.

tokabochi 9 Posted August 14, 2011 Author Share Posted August 14, 2011 Yes, he's pleased Ezorisu. I suppose it could have been a lot worse. I have heard of lots of cars being flooded to the extent that they were damaged far more seriously. The car companies in this part of the world are rather busy right now.

Ezorisu 0 Posted August 17, 2011 Share Posted August 17, 2011 Definitely could have been worse. You're usually good up until the car starts floating - that's when water starts getting into all the "bad" places. Link to post Share on other sites
tokabochi 9 Posted August 18, 2011 Author Share Posted August 18, 2011 I guess the exhaust pipe would be one of those.......... water very nearly rose that far, thankfully not. Link to post Share on other sites
