haha
price = cheap
maintainance = HIGH
problems = alot
when to service = UNKNOWN

No need maintenance la, mine clocked 53k haven't service once....

need...just that we dn't know when only..cuz no sign like disc type
and we dn't know anything abt it either...inside is very complicated..alot of spring and stuff
mine clocked 75k...and i dn't care abt it already ...lazy to care abt it..many problems

I dun see any complication...just a simple structure only....spring is to pull the brake shoes away from touching the brake hub during cruising, and the pump between the brake shoes is to push it towards brake hub during braking...i saw alot of drum brake changed before, and most of them is brake bump leakage...

Whats your problem actually? maybe you are the unlucky one...anyway dun expect drum brake too much, just when you pull handbrake the car can stay stationary at slope is more than enough...

i see them open b4 as well
when they open the cap..it looks simple..1 spring and some part and they opened it somemore inside
lots of small parts inside
and the time and work involved to fix it is a lot
lots of time = high labour
lots of part = high maintainance...need to replace alot of part
last time when its be4 20k..i claim like 3-4 times from SC already
they fix...ok..after like 1 week..its back...and it repeats
got once they changed the shoes...discovered that makan 1 side only...lucky its free cuz they have "1" spare shoes..not "1 pair"
until now still makan 1 side
how i know?...when i change my abs...they jacked it up and i didn't know they pulled the handbrake..i got nothin to do thn go spin the wheel
the left wheel can freely spin...the right wheel is locked...thn i go see..the handbrake is on
useless piece of stuff...now i dn't use it already...even on slope its useless
oh..and the handbrake lever is loose2 one...i ask them to tighten it...after awhile..loose back...loose as in can move sideways loose

ps: changing a brake pad for my disc only takes less thn 30 min
asking them to fix that dam drum brake at SC will cost u AT LEAST 2 hours
open it is easy...putting it back is the hard part...every small part has to go back where it belongs...
some need the screwdriver to pull it into place....sometime i see them use hammer...lots of parts

Then you really unlucky lo...i try to spin my tyre during jack up, both tyre also lock, at slope also no problem...i bet something wrong with your drum brake hose, force distributed unevenly or even one of them is blocked...

I just mean drum brake have better grip compare disc brake for rear. =]

So sorry 2hear re yr probs with rear drum brakes.

I've had drum brakes of previous rides serviced/repaired as per schedule/necessity. The mechs who worked on them were efficient & fast.
Like Bro coolkwc said...very little also to go wrong. Most times it's the brake cylinder unit/pump which leaks. Juz need 2change nia.

Brake shoes are very lasting.

Feel yr handbrake not working as it shld cos of poor adjustment of cables &/ clearance of shoes fr drum.

Find a good xperienced mech 2solve yr probs.

ps. Proton SC mechs are high turnover feature! Diff ones also might b good only in certain aspects. I've seen cases of other mechs unable to handle probs but if got good rapport among them, then one knowledgeable guy might step in.
Here face-saving plays very important role!!

not sure...claim from SC many times already
ask..somemore they say its normal
mean all along this 4 year..my drum brake is makan 1 side
the left side shoes is brand new all along

not just me...i've got a member here...sabah's saga driver also PM to complain abt the drum brake/hand brake...asking me for advice on how to fix
his case is he always go to his uncle's hse...his uncle's house no parking, need to park abit away and its a slope
and even on full pull...it will always go back
and somemore his car is manual...no "P"
if not wrong...he change his cylinder to a bigger one

Yup, just do not simply claimed drum brake is suck becos your own bad experience on that...most car i saw <1600cc also use drum brake behind, and we have to accept it...

Like Zeone said, find a experience mechanics to fix your problem, there are alot outside, why insist must go to SC? even repair outside only cost you once only, rather than you go back SC wasting time and energy and with frust outcome...becos for sure now this is isolated case, if the drum brake really that bad, alot of us sure suffer and complain adi...

maybe will find someone to fix it soon
but in sabah...not so sure which mech is skillful in this kind of stuff
and its not gonna be cheap as that saga driver that PM me say
its bad...and it's not just me that say that
last time when i go my SC...2-3/10 car being jacked up just to fix their drum brake...all claim warranty one
i know cuz i always go back there and see and chat with them

This case is different with urs, at least not brake one side...somemore for manual car you can always put into 1st gear when you no confident on your handbrake...

mine might be makan 1 side
but if i pull it long enough...it still makan...mean the car will stay still but only minor slope(really minor)
mean the right side is holding it ALL
LOL
i just checked back the PM he send me
he said the cylinder is jammed
to fix it...need to repair the cylinder
RM25 per cylinder(both jammed as he said the mech say)
RM18 for a bottle of brake fluid
RM90 for 2 hour labour
after that pull 2-3 times ok already but after 3 week...the number increase to 4 thn so on......
and that mean its not permanent..always need to fork out money to fix it
so its not cheap/time saving...like disc brake
thats why i say disc brake is better

Last time in school,my physics teacher told that drum brake is stronger than disc brake, that's why drum brake is usually placed at the back, to avoid motorcycle from flipping forward, however i find this statement quite...

Base on my experience, drum brake failure are due to:

1. No proper bleeding? air trap may cause brake will be uneven.
2. Brake hose clogged?
3. Using cheapo brake pump? always leaks.
4. Wrong assembly of the brake pump kit.
5. Using wrong DOT brake fluid.

Fr above, feel.... :
1. The bolded part info means it's highly probable that it's an adjustment issue.
2. Need 2adjust cable linkages fr handbrake to back of drum brakes and/or internal clearance between brake shoes & drums. A good mech wld kno how much adjustment needed to equalise braking for both sides.
3. Also mechanical handbrake application does not use the brake cylinders. That's why in case of pedal brake failure, one can still use handbrake to slow down vehicle.
4. If brake cylinders are also jammed, it can tested by spinning wheels off the ground & applying pedal braking.
5. Faulty brake cylinders are better off replaced than serviced cos won't be long b4 prob returns.

Above are my views fr past experiences. Hope of help...

Our Bro's prob is mainly handbrake issues.

wa biang eh ! physics teacher also come out ! boom dou jor !

1.2.5 is not a problem when i see them fixing it
only left is 3 and 4 only

hehehe sorii... didn't read properly..
