Hi All, due to the latest enforcement of PSV license by the Ministry for all E-hailing drivers. Yesterday I took my Produa Myvi 2012 to one of the Puspakom cawangan to do the necessary testing and checking to apply PSV examination.

After the checking, I got 'Gagal' for Brake Test. The overall passing marks for "Brakes" category are 58marks and I only got 50marks, the main cause are due to both my Rear Brake has failed during the testing.

I was shocked as I only took my car for brakes service just a month ago and it failed during the Puspakom test. So, today I brought my car back to my usual workshop and check then we found there is no whatsoever "tear & wear" and "broken" to my whole Rear Brake System.

Since there is no kaput of my parts then the mechanics helps me clean inside the drum, check for leakage of pump, clean up brake pad and he also tighten my rear brake pad near to drum to make sure I can pass Puspakom @ 2nd time.

After the fix, I bring my car back to that Puspakom center for 2nd time testing with confident and I got 53marks which is "Gagal" again. I was really desperate and frustrated as I dont know what the hell is wrong with my Rear Brakes.

Can I know what can I do to make my car Rear Brakes like seriously very "makan" to pass the test?

Prompt feedback is much appreciated. Thank you. cry.gif cry.gif

Im not a pro, be forewarned.

When is the last time you replace your master cylinder?Sometimes it might be caused by worn out m/c. Maybe try to replace the rubber seal on the m/c first? Since your brake seems to work fine under normal driving.

interesting topic.

usually rear brake drum is literally "tak makan"

but since you already dismantle the rear brake drum and check the small piston pump see got leaking anot

another tips if you can post up your rear brake drum photo, it will be easier to judge.

when is the last you replace your rear brake shoe ?

ok, check also your drum cover surface, is it smooth or have grooveline ?

user posted image

check also master cylinder, master brake pump, and when is the last you replace brake fluid ? brows.gif

From what I read in the ehailling fb group, a lot of people faced the same problem. What they did was go to a workshop that fixes a lot of taxi, show them the test results and they'll know what to do.

Alternatively, to make your rear brakes better, change to double layer servo, change brake shoe too.

Ask your mechanic to adjust the pressure .normal standard kilang is 30% for rear

Adjust to 50 50 for rear and front..normally can pass coz eequirement for kerta penumpangis different from normal car

Puspakom test are a pain in the...
What we usually recommend for our customer after checking.
Replace whatever is defective.
Tighten the rear brake until is barely spinning freely. (After the test, please release the rear brake to proper specs)
Drop the rear pressure until 18-20 PSI.
And if you got stuff in the car that are heavy, please remove it.

Usually, we tighten the rear untill you barely can pull on the handbrake ie 1-2 click only.
Your mechanic should know how to get this.

hmm.. interesting, can anyone explain the technical details on why Puspakom is failing it ?

TS never posted what is stated in the Puspakom report, telling us the score doesn't help to know what is causing the fail mark.

Yes exactly, what is the actual reason that the score is low? TS should have asked for more clarification from the puspakom inspectors so can know exactly what to fix.

My dad faced the same problem with his lorry. The
Brakes cannot be adjusted further as it is at maximum. We got our mechanic to be present during the test. And the mechanic explained to the the officer after it failed 2nd time. And they retested again, it passed. But note that this was somewhat more than 20 years ago.


The problem is that you cannot challenge puspakom on their calibration nor competency nor the consistency etc....

Until today, the lorry has no issues nor involved in any incident.

Normally the puspakom will do the emergency brake test on their machine to check out the all the brake condition. Result will shown the mark for each run. Its quite normal for rear brake to fail due to low pressure at rear

Just wondering does the test for ehailing/cab and private car the same? Cause I had this MyVi 2006 tested in Puspakom and passed 5 months ago. And I can say I don't like MyVi's brake because you need to push a lot only it start to "makan". This is apparently normal for MyVi.

The brake test report will ultimately depend on the tester and how hard/ diligently he applies the brakes during test.

Well once I do have the same problem after changing the engine and getting it endorse. Send to the mechanic and they change the break shoes. But he did change both my break pad with original parts and tigthen the break. Gone to puspakom but forgot to put away the old break pad. So it is left on the front passenger sit. Maybe you need to do it that way?😆

Even if you drive a new car just come out from showroom and enter puspakom for inspection also can fail especially brake test, wondering who set the rules for brake distribution.

Car engineer already set the best brake distribution front and rear for best balance when cornering and straight road, after alter brake distribution more to the rear the car no more balance when braking during cornering.
