Hand brake

[Jusnel]

hi,

 

just to ask abt hand brake effectiveness....

 

if my manual car is on the upslope and need to stop, i will normally pull hand brake and the car should be able to stay on upslope.

 

but if my car keep sliding down bit by bit, what is the problem?

 

i already ask ws to tighten the hand brake, but the car still slide down.

 

any parts to replace?

Go to authorised workshop for a 2nd opinion.

1) ur parking brake pads gone

2) ur rear cylinder leak and inside all oil cannot grip

[Trex101]

I second that. Most likely the rear cylinder leak, that why cannot hold the pressure.

[Jusnel]

mine is 4 disc brakes

 

do yr 2 pointers still apply to disc brakes?

[Furrynadz]

disc brake also got drum

[Stivo]

rear disc and drums are 2 different thing.... if your car is relatively new... shouldn't be behaving in this way...anyway go to the dealer for an inspection.. it can be brake fluid, insufficent brake pad or as simple as tightening up the hand brake lever.. word of advise... to the car into gears if you park on slope.. i have seen handbrake cable snapped before ... so take care!!

[Furrynadz]

if u dunno, dun offer comments

ask ur mechanic to cut open ur rear disc and show u the drum

[Stivo]

I know cars with rear disc comes equipped with a drum parking brake... what i meant is drum and dics brakes are 2 different things...

same apply

a drum is not inferior to a disc

buses also use drums

[Stivo]

drum and disc have both its pros and cons else drum would have been obselete by now right??

[Zyrofillica]

drum better stopping power. Disk easier cooling, eaiser maintenance and does not reduce braking capacity when in contact with water.

 

SO is it really true all rear discs come with a drum brake? some pple keep on calling me nooooob when i tell them tt? Is there an supporting sites on the rear/drum brake assembly. I was wondering how can they make my rear axle so FAT if there is nothing inside.

[Jusnel]

the only diff i know between drum and disc is disc is maintenance free, while you got to maintain the drum in the sense that you got to change the inner linings or 'skin' as it will wear off over time.

 

the braking distance between the two is the same.

 

i think its cheaper to put drum brakes on vehicles, compared to disc brakes. tats where some car makers cut costs by offering drum brakes, although its not inferior in any way to disc brakes.......

 

anyway, thanks for yr tips. i will take note of it when i go to ws

pedal operate ur 4 disc brake

handbrake operate the drum parking brake inside ur rear disc

If you do a lot of hard braking, the drum cylinders confirm pichar. Mine did. One side got activation, the other side of the cylinder don't have. As a result, uneven brake shoe wearing.

[Genie47]

Your post makes perfect sense. When I converted my Starlet to use all discs, I used the G7 Rolla's rear disc for the rear. I asked the conversion mechanic why cannot use front since front for the back since front "more powerful". He replied in a deadpan manner: "Got power also no use. How to park and keep it stationary? Use brick on brake pedal ah?" Then he went on to explain why by showing me the internals of the rear disc brake of the G7 Rolla.

One disadvantage of rear disc brake type is the higher braking force required to hold the brake disc and stop the wheel from rotating on a slope during handbrake parking.

As such one has to really pull up the handbrake hard to do that. If the car still move, then, the brake need to be check.

Possible faults are brake pad fading or worn, brake piston on the rear restrictive or jam, brake fluid need to be replaced, handbrake adjustment required.

 

A disc brake is capable of higher stopping power, so in higher capacity vehicle a rear disc is better than drum in stopping power. Maintenance wise and repair should be simpler. However, when the disc is wet, as going through flood or water, stopping is affected initially, once all the water is vapourised the brake efficiency is good.

 

A drum rear brake for small capacity vehicle is more than sufficient for all the braking needs. it is cheaper in cost and functions effectively as well. Anyway, the rear account about 25 -30% of the total braking power.

 

As a guide, the rear brake pads should last at least twice/trice the front pads. That is to say that on the second front brake pads replacement than the rear pad is worn near to min limits.

What i have seen so far on all cars are, hand brake lever is actually activated by cables to the drum brake of rear disk brake. What this means is that there is a brake shoe within the rear disk brake itself. Unless i am ignorant of the standard fittings of new cars using fluid for the hand brake.

 

for your case, i am pretty sure your brake shoe has worn out if you have already asked your mechanic to tighten the handbrake lever cable. Usually brake shoe for the handbrake can last quite long(like what sky8807 mentioned rear brake shoe can last twice as long as the front brake pad) unless you frequently forget to release handbrake before driving or you do lots of stunts .
