Re: Maruti 1000 - Brakes lack the bite Quote:

Since I park the car outside and it rains at night when I start driving the brakes work so good that even a slight touch on the brake pedal and car comes to halt. After a km or two this super braking power goes and brake becomes bad as they were before.
I notice this super good braking when I pass from water logged road, initially when wheels are very much wet, braking is poor but a stage comes when they start working great and when the wheels are completely dry, its bad again.
What I am making out from this is that brake pads when they are moist are working good and after drying they are not working good. So should I get the disc brake pads changed? I got them checked and they are not worn out but pretty old maybe 3+ years
Edit: I remember few months back once a mechanic offered a second hand brake booster and I got it swapped in condition that brakes should work. But there was no difference in braking so I got mine fixed back. Since then I was thinking something else to be wrong with the braking system |
That means that your hydraulic circuit is fine and only the "friction" part not working.
The brakes are not "biting". With water the surfaces are wiped clean, friction increases, and the brakes become effective. Here is what I would do
1. Clean the disks and the drums with kerosene or diesel to get rid of all the oil/dirt. Use a fine sandpaper (preferably the wet&dry) to polish the surfaces.
2. Clean the brake pads and sandpaper them as in point 1.
3. Now check if the brakes are working, in dry mode. If not wet then thoroughly and check again.
If the brakes are only biting when wet, then there is excessive travel required. Get the mechanic to adjust the travel.
By the way, have you ever changed
- brake oil
- rubber seals all round including in Master Cylinder (I think there is a brake kit, available with all the relevant rubber parts)
If not, do that before any thing else. For all my Marutis - 800, Esteem and AltoK10, these are supposed to be carried out at 40K-60K interval. |
