Had my 25k service
http://www.team-bhp.com/forum/long-t...ml#post1418088
It seems They've used Transpower TQ gearbox oil

As per Tata Motors Customer Care :: Recommended Products

Castrol Extreme Pressure 80 EP should be used. the Transpower TQ is recommended for sumo etc.

Will this be an issue ?

I would like to get some expert help for the issue that I face in my Indigo.During my drive from Kottayam to bangalore last week, I felt the brakes has lost some bite and towards evening when I almost reached bangalore, found that brakes were almost like failing.
I have given the vehicle to Manipal motors on old airport road on wednesday. The mechanics there have tried all stuff to figure out the issue. Initially, they did bleeding to vent out any air inside, later they replaced the brake master cylinder. Still, the brakes don't seems to have the bite

What I experienced is, when I start the vehicle in the morning, the brakes has the bite but upon driving for some 100 m, it starts loosing the bite. There is no decrease in the brake fluid level.
The vehicle is in the service centre for past 3 days, still they haven't diagnosed the issue

Can some experts over here tell me as to what might have gone wrong ?

No expert in any means, but when were the brake liners last changed? And why did they replace the master cylinder? Were you hearing a noise while applying the brake?
Anyways, even if the master cylinder was replaced, it might be insufficient. There's the brake booster as well. Did they find this booster to be alright?

[greenhorn]

are the wheels rotating freely ?
might be that they are gripping the disc slightly and getting heated up with running

They are checking the brake liners now. The entire brake booster assembly was replaced 2 months back. There is no noise when braking.

Check for a cracked or leaking brake booster pneumatic hose. Replace the brake oil unless you have done so already very recently. Replace the brake pads if they appear shiny (or clean them with emery paper). Check for oil/grease on the discs, or a small brake fluid leakage dripping on to the discs when the brakes are actuated. Clean up the discs with emery paper also. Also check for cracks on the discs, and replace if necessary.

This is the second workshop that I am showing the issue. Earlier, I went to Prerana, where they did some bleeding and returned the vehicle. The brakes had improved a bit but later found that they are back to square one. Now with Manipal, they are again removing the wheels and checking the discs/liners.

Check break "bosh". that`s what they call it in machanic lingo. See its a round thing inside the bonet and there a line going from it to the engine where vacuum is created. I don`t know what it is called technically but mechanic calls it as break "bosh". i had similar issues with my sierra where if i pressed the break it just wouldnt work.

To test weather this break bosh is working or not, just put your leg on the break peddle and start the car. if the peddle is getting pressed, then this "bosh" is working perfectly.

I have got fed-up with the flat tyre issues for my trubo v2 Indica. Two stock tyres have got internal beeding opened and this has resulted in the damage to tubes resulting in flat tyres.
Please let me know if i can replace only these tyres with the new ones. My plan to have new tyres for front wheels and retain the existing tyres for the rear wheels.
Due to this will their be any alignment problems or any other problems. The existing tyres have run 40K Kms.

Have got a quote for BS tyres
165 65 R 14 - 3400/- tube + tyre
175 65 R 14 - 3300 - tube + tyre
175 65 R 14 - 3400/- Tubeless.

I think it is the brake booster that you are talking about. The brake booster was replaced ( entire assembly) 2 months back

[greenhorn]

think its better asked in the tyre section

[tsk1979]

40K kms is a lot of running. Get Tubeless tires for all 4 tires.
If you are planning to upsize from 165/65R14, the correct upsize is 185/60R14
If you do not want 185/60, stick to stock size 165/65

I am using apollo acceleres for quite some time now on my indica, and they are working great. Been through 2 sets now.

There won`t be any problem if you change just the front tyres. However, make sure they are of the same make and model as rear. Also, after you change the front 2 tyres , just do the alignment.

ohh sorry, i forgot to read 40 k kms. In that case its better to replace all the 4 tyres.

Finally,caught the issue with my Indigo brakes. Manipal guys spend whole 3 days checking the car, tried with new brake booster,master cylinder, checked brae liners,discs.Nothing helped.

Finally, they came to what should have been done at the beginning
The culprit was the brake fluid rubber hose that is supplying the fluid to the front wheels. It seems, last time, Prerana motors had replaced the brake fluid cable with a sub standard cable and then, upon heating, the fluid hose expanded,thereby,taking in more fluid.

This really explained what I experienced,viz, initially, brakes were fine, but on running more than 100 m, brakes start becoming spongy.

AT the end, everything is back to normal.Before going to manipal, I went to prerana and they had only one solution: replace brake booster again ( which I had replaced 2 months back)

Now, I have a gut feeling that the previous replacement itself was not warranted, had they checked the brake fluid hose.

But, trust me, first hand visual inspection might not help diagnose the issue and hence am not really finding fault with them, but, then, I am not sure why they replaced the brake fluid hose with a sub standard one.

If possible, check the part numbers of the two brake hoses. Maybe it was just a bad piece!
