| 591921 | 2007-09-17 04:59:00 | i went for a WOF and the people said my brakes are imbalanced. the brakes work and they don't need to be replaced,but their imbalanced. How does the mechanic balance ur breaks and how long does it take and whats the cost? THanks |

| 591922 | 2007-09-17 05:03:00 | It's usually a function of something sticking or something else NOT being activated. Rare condition..what kinda car? |

| 591923 | 2007-09-17 05:20:00 | One of the hydraulic pistons that move the brake shoe or disc pad could be seized causing an imbalance of braking between the vehicle's wheels. | gradebdan (2186) | ||
| 591924 | 2007-09-17 05:30:00 | Find the steepest hill in town on a quiet day/night; speed down it fast as you can then slam on brakes to a screeching stop. Repeat as required until they even themselves out. :D | Greg (193) | ||

Repeat as required until they even themselves out. :D Not a good idea...you'll just succeed in overheating and possibly burning a rotor or drum that way......but I need to sleep..it is 22:00 (US) here and I am tired.. I'll get back to you with a long tirade later tomorrow.hopefully you can wait for that...OK? |

| 591926 | 2007-09-17 06:03:00 | which brakes where out of balance? commonly rear drum brakes tend to 'back off' and may need to be adjusted. disc brakes can seize a calibre but i would think you would notice the other side locking up ;) could just be galzed pads. sometimes giving them a thrashing will clena them up, otherwise need to pull the pads out and give them a quick sandpapering. i'm sure joe will have better suggestions ;) |

| 591927 | 2007-09-17 07:17:00 | i went for a WOF and the people said my brakes are imbalanced . the brakes work and they don't need to be replaced,but their imbalanced . How does the mechanic balance ur breaks and how long does it take and whats the cost? THanks I had this problem on my old Cortina . One of the front calipers had seized . These things are usually not serviceable, so I had to buy a new one . Another cause could be an airlock at one of the calipers . The simplest thing to do in that case is to bleed the caliper . There should be a relief valve on it . And if you are going to bleed one caliper you might as well bleed the whole system and change the brake fluid . And oh, unbalanced braking can cause you to lose control during high-speed braking . Even a very slight imbalance . A bit like trying to brake with one front tyre on gravel and one on tarmac . |

| 591928 | 2007-09-17 08:20:00 | heh I have just found out after 70K kms, that one of the brake pads on the inner rear has never worn down . Its never even touched the disk . It been stuck the entire life of the car . I only found this out when getting the brakes replaced . It passed all the WOF's over 8 years . The ABS seems to have been compensating for the entire time . |

| 591929 | 2007-09-17 09:34:00 | Brake imbalance is from the WOF brake rolling road test I think the brakes have be equal within 5%. Its not front or back sets its each side. So the car would pull to one side if the brakes are put on. I guess you own a japanese car ( I dont because of what they did in WW2) Brake adjustment on drum brakes normaly at the rear wont fix an imbalance. Adjustment just takes up slack or travel. The problem is one side isnt working as well as the other. If the imbalance is say on the back rip both the drums or disks off and get them machined, get new wheel cylinders if drums, replace the shoes or disk pads. Adjust the shoes so they are just touching, drive around with brakes on a bit to get hot and brake on some gravel, get out and look at skid. Always do brakes in sets ie front or back together. There are tricks to get thru wof by changing tyre pressures on each side or making the good side equal the bad side by ******************* ha ha wont tell you how. tedheath |

| 591930 | 2007-09-17 10:34:00 | Check clean & adjust your brakes. If all is well with nothing seized or brake linings contaminated, then your brake proportioning valve is faulty. Most likely because the brake fluid has never been changed & it's rusted up internally. You can try 2nd hand for replacement, but it doesn't cost much more to get it rebuilt, at least you know it will work. | Phil B (648) | ||
