One of my friends wants to upgrade his rear brakes to disc and if possible add ABS! I know its pretty expensive affair with risk of unreliability!

Upgrading to disc brakes at the rear is quite achievable but adding an ABS is just next to impossible

.Simple reason that the ECU wouldn't support it. BTW what car is your friend talking about ?

I think Jesal had converted his zen's rear brakes to a disc setup after an engine swap. You might want to check with him.

Sorry guys forgot to name the car. Its a Hyundai Accent!
Yes. Even i had advised same to him. Not to try these after market option!

Being a petrol head and electronic heart guy, moment he told about ABS i thought "will ABS be supported by existing ECU"

Also the reliablity if done after market!

Many thanks for replies

Can a car with existing ABS and front discs-rear drum setting be converted to all disc?
The car here in question is my i10.

Bumping up an old thread

What would be the implications of changing the rear drums with disc brakes using OEM parts?
The car under consieration is Verna 1.5 CRDi SX (non-ABS). Verna 1.5 CRDi SX also came with the abs version with rear discs.

So, can the rear drums be safely changed to discs at the authorized servcie center?
Any chances of wheel locking by converting to rear discs (no ABS)

^^ Answering my own question.

It is possible, more info here(need to go through most of the discussion):

In fact some of the earlier generation cars came with all 4 disc brakes without ABS:

Dear Sirs,

Most low to medium priced cars in India come fitted with front disc brakes and rear drum brakes combination. However some expensive imported cars have all wheels disc brakes.

Is it possible to change the rear brakes too into disc brakes ? What are the benefits, disadvantages and costs in India ? Are there certain specifications and legal aspects?

Warm regards.

Technically switching from drums to discs is definitely possible. The issue is quality of work and cost. Accept that barring a few specialists, most people will not be able to get anything close to factory finish. Considering it is the brakes we are talking about, do you really want to get it changed. A botched job and your life is potentially at risk.

Additionally be aware that unless the job is done by an A$$, and even then, they would probably void any warranty. Assuming the warranty period is not an issue, it may become an issue with insurance refusing to pay in the case of an accident.

All said and done not really worth the headache of getting it done.

Let me tell you, even with all four discs , 80% of the braking is done by the front brakes. So disc or drum at the rear does not matter unless the car is fitted with ABS+EBD. And all the cars which have the mentioned combo have all 4 discs. So retrofitting is no use. Keep the drums in top shape and you are good enough

Altering the brake system would require you to inform the RTO of the update, and require a fitness to be done. Please bear this in mind.
