Do I need a Brake Job ?

Rotors can undergo warping from overheating and rapid cooling, from poor torqueing of lug nuts or bolts, etc. But warp is not the only problem that can occur: variation in disc thickness can cause pedal pulsation, as can improper machining or reinstallation of a disc (rotor).

I NEVER let a tire shop use anything but a torque wrench to put my wheels back on. I do not trust the torque stix because I have been burned by them on two separate occasions.

A local tire shop here uses impact wrenches to put wheels back on, and when I go there on occasion, I pack my own torque wrench to let them use.

I heard a similar story from some engineers myself, but their explanation was that in their experience the slight but non-zero risk of introducing crud into the ABS hydraulic control unit during a flush was actually greater than the risk of component failure due to corrosion during the expected service life of the vehicles, which I think was pegged at about 10 years, and this was the reasoning behind not recommending regular fluid changes.

Several things we can learn from this:

1. When doing pad changes on an ABS-equipped vehicle, one should open the bleeder screw on the caliper before compressing the piston, and then top up the reservoir with fresh fluid if not performing a flush. If they're worried about contamination from the MC, then contamination being back-flushed from the caliper is probably an even greater concern.

1. If you *do* choose to flush, it would probably be advisable to suck the reservoir dry with a turkey baster or suction gun, and manually clean out any floating debris evident.

2. If you plan on keeping your vehicle longer than 10 years, the factory recommendations may not apply to you, and you may want to consider regular flushes.

What proportion of all cars on the road use the Teves system? Did the original poster's car use the Teves system?

And what the f*ck is the teves system, anyway?
