    Default Replacing drum brakes with Disk brakes

    Hello all I have a 92 Suzuki Swift and I want to know if their is any shop in Karachi which can replace my cars rear wheel drum brakes with disk brakes. And if so where can I find such shop and how much would it cost, since the fact is well known that disk brakes are better at stopping cars the drum brakes are.
    Thank you.

    The couple of mechanics i've talked to didn't say anything about changing the handbrake setup, the reason i need to change it is that the brakes are a bit too soft for my liking even though i've serviced my stock brakes it doesn't stop my car well as the 11 camry does. It has disk brake's and stops very well and i don't have to press my brake pedal down too much, in fact i've checked and driven a couple of other cars which contain disk brakes and drum brakes in each of them the disk brakes beat the drum brakes in stopping the car faster, better and safer. Thus the reason for looking for drum brakes for my car.

    IS their not even an aftermarket version of disk brakes available for the car? As it is said that many aftermarket parts are available for cars in the car markets?

    Never go for alteration or after market local parts as safety does matter and brake isn't a piece of cake can end up to death

    92 Swift is essentially one of the first versions of Khyber before the Suzuki company gave that design to Khyber and then changed the Swift's design afterwards so if you want to see the swift just look at any Khyber on the road right now since all the part's are the same as the Khyber.

    @aijazkhalid, the 1992 Swift was sold in a 2 door configuration as the Cultus GTi in foreign markets. IF this car came with rear disc brakes, you might be able to use them for the swap, though I highly doubt any stuff for those cars is available in our junkyards.

    A few words of caution before you go on a wild goose chase now:

    Converting to rear discs doesn't automatically solve all your braking issues. The front brakes do >80% of the braking. The job of the rear brakes is to provide additional drag while keeping the car's rear end straight and planted firmly on the ground. Just one look at the size the tiny drum brakes on the Swift should give you a hint of how little work is expected of them. Almost any disc brake conversion you do that is not OEM for this car will be larger in size than even the front brakes causing very poorly balanced brakes and a car that takes even longer to stop.

    Rear disc brakes also require swapping to a larger diameter master cylinder and possibly bigger booster as well because of the greater volume of fluid required to operate 4 wheel disc brakes. I installed rear disc brakes on my Jeep CJ7 recently, and I still had to change the master cylinder as the pedal would sink all the way to the floor with original cylinder. Keep in mind, I didn't even use an oversize performance set up, just Suzuki Potohar discs with Corolla rear calipers (same as 86 Pajero rear calipers, but easier to install). Braking is pretty much the same as before, the main improvement being in pedal feel, brake modulation, and vehicle pitch. Now I need to modify my parking brake cables for it to work with the disc brakes. That's something you'll also have to worry about too.

    All in all that money would have been better spent on other things. It was not inexpensive and the improvement really is marginal. If you want to improve braking performance, look at upgrading your front brakes (larger discs and calipers) first. Also remember that larger alloy wheels and oversized tyres ruin braking performance. Lastly, remember that a 1992 Swift will never have the same braking performance as a 2011 Camry, short of installing Brembo binders that cost more than the car itself is worth.
    Anyone likes this.

    You said to look into upgrading the size of front brake disks and calipers. So from where can i get the Best quality and resonable priced disks and calipers from in Karachi and how much should it cost me to have it replaced by my mechanic?
    Thanks.

    You need to talk to a mechanic who specializes in alterations, and he can guide you best about which discs and calipers to use. The parts are available in Magazine Lane behind Tibet Centre (Plaza) or Shershah.
