Pros & cons of hydraulic clutch - Team-BHP

sbasak · 2nd February 2007, 15:54

Why some cars use hydraulic clutch? Is there any advantage?

One disadvantage is that you need to check clutch fluid level and top up when necessary.
A garage mechanic told me that with hydraulic clutch, clutch wear is less prominent to feel as hydraulics compensate the clutch slip. Is it true? If yes, that means hydraulic clutch fails without warning

(unless you keep a close watch on rev counter for high revs at lower speeds).

Personally from driving point of view I don't feel any difference between normal and hydraulic clutch though later feels like slightly harder to push.

Hydraulic clutch is self-adjusting for wear.

Hydraulically actuated clutches are better in most aspects; for one, it gives consistent pedal feel throughout the life of the clutch. Although, when the clutch fails, the pedal WILL show reduced play; same case with the pressure plate as well.

A few drawbacks of hydraulic clutches include risks of master cylinder leakage, slave cylinder leakage, etc. But then, the cable-actuated mechanism suffers from risk of under-lubrication and requires constant care in terms of adjustment as well.

Simply put; hydraulically actuated clutch mechanisms are better suited for handling high-power/ high-torque applications.

Can someone please list some cars that have hydraulic clutches and some that have cable operated ones ?

OHC's have [bowden] cable. Civic has hydraulic.

800 must have cable :-)

Hi,

I think almost all Maruti's have cable operated clutches, OHC cable, Hyundai Accent & Getz hydraulic, Santro cable, Lancer cable, NHC cable, Optra hydraulic.

Thats all I can remember off hand.

PS - Am not 100% sure so please correct me if wrong.

The ikons and fiesta's incl fusion are on cables....

mithun · 6th February 2007, 07:45

Is there any other types of clutch systems other than the Hydraulic/cable operated systems ?

moralfibre · 6th February 2007, 10:42

The clutch on the Palio, Petra, Adventure and Siena is hydraulic.

austere_sly · 9th May 2007, 18:20

Swift got a hydraulic one.

Jaggu · 10th May 2007, 00:25

ikon is cable?? are you sure?? i think its hydraulic

swift D is hydraulic, swift p is cable

wolfinstein · 10th May 2007, 00:28

Lancer is Hydraulic..I think..!

Hydraulic clutches rob you of some feel, or so I feel.

Jiggy, IIRC, the older Accents were cabled. The 1.6 ones have hydraulic clutches.

The Standard Herald was the first Indian car to have a hydraulic clutch.

Akshay,

All accents sold in India were Hydraulic only. My sis had one of the first lot of entry level 1.5 Accents sold and they were Hydraulic.

Santro is hydraulic too. I had a hard time getting used to not so precise feeling of Santro hydraulic after upgrading from 800 and Esteem. Hyundai service manager accepted that Esteem cable clutch is much superior to Santro hydraulic for it's precision operation and accurate feedback.
