Re: Honda recalls 31,226 units of Amaze & Brio for brake inspection I'm pasting below an extract from http://www.livemint.com/Industry/9nh...or-checks.html
"The company said on Monday that it had noted a possible defect related to the proportioning valve, which adjusts the rate of increase in the pressure on rear brakes and helps bring the car to a smooth stop, preventing the brakes from locking up. No complaint related to the part has so far been reported, it said.
“HCIL will voluntarily replace the proportioning valve after inspection, if required,” the company said. “The inspection and replacement would be carried out free of cost at HCIL dealerships across India, and the owners will be contacted individually in a phased manner.”
The inspection would be carried out on only those variants the Brio and Amaze that do not have an anti-lock braking system (ABS).
“Proportioning valve is not a part of braking system for ABS variants and, therefore, the ABS variants of Brio and petrol Amaze and all variants of Diesel Amaze do not require any inspection,” HCIL said."
I have two questions;
1- Why is a proportioning valve which according to the extract above adjusts the rate of pressure on rear brakes and helps the car come to a smooth stop absent from the ABS version? I always thought that ABS was an additional mechanism/system added to a non-ABS version of a car. The above seems to imply that they take a component (proportioning valve) out of the Non-ABS version and then an ABS system to it. There may be a technical logic behind this- but I am not aware of it. Can anybody explain?
2- Why does the Diesel Amaze (both ABS and Non-ABS) NOT have a proportioning valve at all. I hink- with the increased kerb weight and heavier engine on the front- it should definitely have all the safety features of the petrol and much more. So why does the Diesel completely miss out on this valve which assists braking to the rear wheels? Cost cutting because the Diesel version is already very expensive or something else? If it is cost cutting- thats a nasty way to cut costs! Reminds me of the old debate of the braking of the L&V versions versus the Z version of the Swift!
