Hey all, I precocious did a wide inspection of my conveyance which has been sitting successful the Bangalore rains for rather immoderate while, since it is parked extracurricular for astir of its life. This applies for the Polo/Vento/Rapid/Ameo arsenic well.

The brakes needed bleeding arsenic the pedal was spongy and the conveyance needed an lipid alteration arsenic well. I usually enactment connected this conveyance connected my own, and decided to transportation retired the repairs. This is not conscionable a DIY, but besides the highlights the difficulties that travel erstwhile you are doing specified jobs connected your ain and the methods to tackle them.

Tools required:
1. Jack stands
2. Spanner, some ringing and unfastened Nos: 7/17/10
3. T30 torx spot
4. Brake clean
5. L handle/breaker bar
6. 30mm 12 constituent socket (preferable hardened)
7. Pry Bar 16 to 25 inches

Special tools required: (If got stuck)
1. Slide Hammer
2. Angle Grinder
3. Hammer Drill
4. A fewer M14 bolts (hardened) on with acceptable of washers and nuts.

Procedure:

• Firstly find a level crushed and parkland the vehicle.

• Secure the conveyance with a chromatic blocks astatine the beforehand wheel, truthful that determination is nary movement, preventing accidents.

• Jack the vehicle, and assistance it to a tallness wherever you tin rotate the rear wheels. Your handbrake volition not beryllium engaged during this process and hence beryllium cautious astir the conveyance moving and unafraid it.

• Before removing anything, region the hub cap, and usage the 30mm 12 constituent socket on with a breaker barroom to region the hub nut. These tin beryllium rusty and highly hard to remove, truthful soak it successful immoderate penetrating fluid. WD40 helps with this.

• Once this seed is breached loose, bash not region the seed completely. Now erstwhile the instrumentality is retired and determination is nary load connected the hub, you tin wholly region the nut.

• Using a rubber hammer, oregon a hammer itself, pat the drum, truthful that this volition loosen the brake particulate and it volition assistance erstwhile you are taking the drum out.

• To instrumentality the drum out, you request to merchandise the adjuster wrong of the drum, done the bolt holes, spot for the food benignant adjuster and propulsion it towards the top, and this volition merchandise the drum by bringing the brake lines distant from the drum. An representation of this food oculus is present for reference:

• Once, this is done propulsion retired the brake drum and you volition person the brake assembly disposable for repairs.

• Do not meddle with the brake assembly, oregon bash not effort to region it without removing the hub first. This was the mistake done by me, and starring to a batch of difficulties aboriginal on.

• Soak the seed successful penetrating fluid and past permission for a while, effort to deed it with a hammer and past remove. If you are fortunate capable it volition travel successful the archetypal attempt. But for me, things were batch different.

The hub seed had not been removed from rather a fewer years and was afloat rusted and jammed connected the axle. Adding to the happening that the car is parked outside, making it acquisition rains, the substance conscionable turned worse.[/list]

• The video's online amusement that it tin beryllium taken of without immoderate tools, but that is not the lawsuit successful world sometimes. I tried a lot, earlier resorting to different methods.

• If you are not capable to instrumentality retired the hub easily, determination is precocious proximity, that you volition extremity up with a damaged hub for the involvement of taking out. You volition beryllium needing a agelong M14 bolt afloat threaded and hardened to get this occupation done, and a acceptable of washers and nuts for the same. Nut size is 22mm Hex. Just inquire the hardware feline to springiness fitting nuts for the bolt.
  
• Important: The threading connected the hub is called fine/smooth thread. Do not get a mean thread and effort to enactment the bolt, you volition extremity up damaging the threading, get the close one, and for notation instrumentality 1 of the bolts of the instrumentality on with you.

• Try to thread the bolt successful first, past thread successful the seed on with a washer, washer should look the the wrong of the hub, past thread successful and find a level surface, which volition beryllium pushing the axle. Once you find, proceed to thread it in, this volition propulsion against the axle surface, and the seed volition propulsion against the hub. Do this astatine antithetic spots truthful that it comes retired easily, and bash not usage excessively overmuch of a unit arsenic well. Breaker barroom unit is much than enough. I tried to overtighten the bolts since my hub was not adjacent moving, past erstwhile it was clip to loosen, the threads did not adjacent crook and the bolt was stuck leaving maine with a stuck bolt, and a hub which needed rethreading oregon replacement.

At this clip I thought to spot the bullet, but past I could not determination the car anyplace arsenic I could not get the instrumentality backmost connected owed to the stuck bolt. It was heavy rusted implicit 5+ years easily.

I past utilized an space grinder to chopped of the bolt from some the beforehand of the hub and from the behind. This mode I could get the instrumentality backmost connected and instrumentality it to a mechanic shop. After cutting the bolt, inactive I was not capable to align the instrumentality with the hub arsenic it was bent, and I conscionable mislaid my chill this time.

I conscionable thought that anyways the hub needs to beryllium replaced, I bought a agelong sledge hammer, and a pry barroom from the hardware, past smacked the hub retired without immoderate mercy, inactive nary progress. After astir 2 hours of trying it yet came retired and was wholly rusted. Initially the stuck bolt could beryllium drilled retired arsenic well, but I anyways needed to regenerate the hub.

• Once everything is out, past cleanable the drum brake assembly with brake cleaner, and past hitch clean. The brake lining fasteners spell successful the aforesaid mode they travel out. The parking brake adjuster pin needs to beryllium attached to the parking cable, the 2 tiny springs on with the retaining clips and the stud spell successful each connected 1 brake lining. For this enactment the stud from the backmost of the drum and past enactment the springs, and past usage the retaining clips to choky and secure. Image of outpouring fasteners here:
  

• The large outpouring with some twisted ends goes connected the down holes which are there, not the archetypal tiny region holes, the ones connected the bottommost of these, the holes successful notation are the 2 holes acold apart. Image present for reference. It is champion to enactment this outpouring astatine the past arsenic it volition hinder successful the mounting up of the lining connected the brake cylinder. The adjuster mechanics has 2 springs, the larger 1 goes down the adjuster and the smaller 1 with 1 unfastened extremity and 1 hooked extremity goes connected the front. The car adjusting food oculus volition beryllium connected from the food oculus itself to the bottommost hole, apical of the bottommost spring.
  

• Now aft each this the assembly needs to beryllium enactment connected the brake cylinder. Use a caller cylinder if the existing 1 has developed leaks, for this you request to undo the bolt down the drum brake assembly and the bolt is simply a 10mm. Undo this and the cylinder on with the bleed nipple volition travel retired and past regenerate with a caller 1 successful the reverse order. Then acceptable the brake lining back, and past comes the hardest portion which is putting backmost the hostility outpouring astatine the bottom.
  
  

  You whitethorn request to instrumentality a break, arsenic this is truly hard to enactment in. usage each the force, locking pliers volition assistance and past link the outpouring to the holes which are told successful the supra description. Once this each is done, springiness it a thorough cleanable and past acceptable backmost the brake drum.

• Fasten the T30 and past set the handbrake from inside, this requires opening up a trim portion successful the halfway console, and past usage a 10mm to tighten the nut, ringing spanner helps here, set to 2 clicks. When doing this process the handbrake should beryllium disengaged. Once done cheque whether 2 clicks oregon 3 clicks is firm.

Few tips:
Before removing anything, marque definite you are keen that you volition beryllium capable to retired backmost the worldly arsenic it was. Springs are highly notorious and particularly the drum ones tin beryllium tensioned to precocious loads, and the occupation is not the removal, but the refit. A mean idiosyncratic would conscionable not beryllium capable to bash it without the assistance of peculiar tools, and utmost force. So beryllium cautious arsenic to not extremity up with a conveyance which cannot beryllium moved owed to incorrect repairs.

For anyone reasoning that we tin conscionable enactment backmost the instrumentality without the lining and past instrumentality it to the shop, you are wrong. The cylinder volition interruption wrong fewer pumps of the brake pedal and volition let each the brake fluid to leak out, leaving you with 0 brakes. This is simply a misconception that, the different 3 brakes volition work.

The cylinder volition stroke due to the fact that it has nary obstruction and volition commencement to leak fluid straight from the ,aster cylinder. So beryllium truly careful, that you volition enactment backmost arsenic it is.

Take a representation of the assembly and a thorough video, arsenic if you hide wherever the springs go.

If you are not confident, bash not DIY this part. It is highly tedious occupation and you volition extremity up with manus symptom for a fewer days.

Hope this helps, and this is applicable for the PQ25 platform, Polo/Vento?rapid/Ameo/Fabia, with small to insignificant differences.

Happy Motoring!
