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 โ€œnotโ€ touch much on the brakes as they didnโ€™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.
