Braking issues at low rpms on my Maruti Jimny: How Im getting it solved

Post the brake cleaning process, the pedal became spongy and I had lost the brakes all together.

BHPian purohitanuj recently shared this with other enthusiasts.

I earlier shared about braking issues on my Jimny. I now have an update on the same.

As per my scheduled visit, I reached the service center where I was informed that few engineers from Maruti Suzuki were waiting.

They connected a VCI OBD and started to capture all parameters as a log file while they drove my Jimny and tested the brakes at different RPMs. I too then drove. Nothing out of ordinary was observed.

Note that the VCI does capture the vacuum brake boost pressure in kPA.

I suppose they will correlate this data from another Jimny tested similarly in higher altitude.

The brake fluid filter had this gunk like substance.

Brakes were cleaned. When I asked them to bleed them once, the service engineer told me that they were specifically asked to "not" touch much on the brakes as they didn't wanted to disturb the brake setup too much for future analysis.

However, post the brake cleaning process, the pedal became spongy and I had lost the brakes all together. Hence they had to do the bleed process which resulted into this oil coming out which was filled in by a brand new bottle of DOT3 brake oil.

During the brake shoe removal, a pin ( which is used to hold the brake shoe) broke which might have resulted in the spongy brake pedal.

The pin is marked as part number 6 in red.

As for the update further, I have asked to wait for few days / 1 week.
