تعديل فرامل الانوس واستفسار صغير

[prince2005]

i have no idea why did Daewoo use this pathetic setup on the 1.5 SOHC cars... the car is heavy indeed and that is the most critical issue here... other cars that weight less tha the lanos can do with such setup but this car simply can't

also bear in mind that this car was developed in 1997 and production was seized at 2003 so forget about any future development or enhancements

thanks very much for this professional explanation.I understand that this as you said pathetic system is not that efficient and should be tuned but my car is new and it hurts when you start getting head over heels so suddenly.When I hit the brakes pedal i feel that the car uses its front wheels only and the rear donot exist at all.

[MMamdouh]

rear brakes does some 30 or 40% of the work... the rest is on the front which is very weak

the 1.6 DOHC lanos go the very same rear brake setup as ours... even the 1600 nubira got the same setup as well... the front is the real problem here

But do'nt you think that the Nubira has better brakes?I think so because I tried it before.Tell me are they different?or as you said because of the size of the rotors as well as the pads?

[MMamdouh]

the nubira got 256mm front rotors and those are as big as the ones i use on the lanos upgrade (the rotors are not identical though) and the brake pads are the same for both cars

the nubira does suffer from the pedal response issue due o the rear drum setup

So what do you advise Nubira's owners? If you want to give rating to both cars(lanos&nubira) for the brakes what do you suggest?

[MMamdouh]

Lanos: front upgrade is a must... rear upgrade is optional

Nubira: rear upgrade to disks is a nice upgrade

most important is the pads type... those should be matched to driving style... if you are a hard braker use a hard compound pads like the Turkish Besher or so... but note that those pads won't perform untill they are hot

if you use brakes gently use Gold or Genuine pads... if you don't ever get excited while driving and never go to high speeds then you should use the Japanese pads (can't remember the name right now)

So you came with the bottom line,front upgrade is a must.This mean that the size of the rotors in the front will be bigger than the rear ones? this will also include the rims.The question is :does this affect the stability of the car?because this will mean strong front brakes and weak rear brakes.I once asked myself how the Manufactured company should allow the car to leave the plant with such poor brakes?

[MMamdouh]

well.. theoretically you should change your proportional valves to compensate for the stronger front brakes... i tried both the 3/40 and 3/30 and found no difference in braking power distribution

MMamdouh

Ok,so we are going to have bigger rotors in the front and small in the rear?Another question,how can i tune the rear brakes(not upgrade)
thanx for your patience&cooperation

[MMamdouh]

by using the 3/30 proportional valves as i told you before...BTW those will make your rear brakes weaker not stronger as you have more weight shifting to the front after the upgrade
