Hi guys,

just want to ask how do you know, na kelangan ng palitan, may sira, or may problem sa mga toh:
1. Brake Pads - pag maingay na.
2. brake Shoe - pag maingay na din or mahina na.
3. Drum Brake (kung madumi na) - pwede linis yun. kaya lang pinapalitan din yan ng pads.
4. kung may problem sa Hand brake? - adjustment lang.
5. Brake Piston <= ewan ko lng kung tama ung tawag ko dito.. hehe - pag may tagas (brake master).

salamat po!!

replies above.... although partial lang.

1. Brake pads - use a flashlight with or without the wheels removed to see how far deep into the brake rotor the pads are worn in. This is the traditional method. The more difficult method is to take the pad out and see for yourself. The last method is to rely on a car with brake pad wear sensors.

2. Brake shoes - this one entails the rear drums to be removed. Check the shoe lining thickness. Metal to metal contact merits replacement (and hopefully not of the drum itself). If the thickness is good, you can adjust the drum springs I think.

3. Same as above.

4. Some hand brake levers need only a few clicks. Check your recommended number, if it's beyond that adjustment is necessary, and/or shoe replacement.

5. I think you mean brake pistons/calipers. These ones have a rubber boot that is supposed to protect the piston inside from dirt. Remove the calipers from the car, clean them thoroughly with brake cleaner (be careful not to inhale the dust), check the rubber boots. On fixed calipers, the boots are in the piston. On floating calipers check the boots that hold the floating part of the caliper in place.

Do not let the calipers dangle by the brake hoses. That will place immense stress on them.

mbeige - thats pretty thorough stuff ;)

mackkcam - if you are getting this done at a Proffesional Auto Shop, don't be afraid to jump in and watch the mechanics working on your car, you will definitely learn a lot, One of the advantages of being here in the Philippines is that you can actually get into the work area and hang around unlike back home in the states where they are concerned about lawsuits and insurance.

What i like here in Baguio is i get to rent the lifter from the shop and i work on my own cars

If you are friends with the mechanic they will often let you in the shop and show you what's what. But in general, yes it sucks but they're afraid of lawsuits in case the customers are harmed in the shop.

The American society fears liability...getting OT though

Thanks guys for your replies,
hmm, I dont think I have a problem with my front brakes, but I have just noticed something when I'm hanging down a semi-steep road (downward; hood pointing downwards) when I have lifted the hand brake, and slowly release the brakes (making sure that the car would'nt slip down, hehe) there is a tok tok tok sound coming from the rear, and the car, very very very slowly, runs down the hill, very very slow though... I dont know which is the problem, the hand brake needs adjustment or the rear brakes... hmmm

[mbeige]

I think you'd have to check both. With your handbrake/E-brake engaged your car should hold the hill. You could either have slack in your handbrake cable (which is adjustable) or the rear brakes are worn. I think your City has rear drums as the rear brakes, correct me if I'm wrong, but if that's the case they might be worn down already.

Just lift the rear axle, remove the wheels, remove the drums. You should be able to see if it's worn down right there. The shoes should still have some material left. If not then the metal part will be biting against the inside of the drum, which doesn't provide much grip, so your car crawls slowly. My guess is there's very little material left.

Thanks mbeige, I'll have it checked during the weekends...

follow up question on brake shoe: aside from ocular inspection, how i would i know that it needs to be replaced?

If you replace your disc brake in front for the third time, its about time to change the shoe on the rear brake too. But you must inspect visually and clean the drum, shoe w/ brake cleaner whenever you change the the front disc brake.....for safety reason.

visual inspection is really the only way to tell what needs to be replaced.
