men kan man få bättre nyp i orginal bromsar med andra bromsbelägg
eller är det bara att byta skiten . helst byter jag bara bromsbelägg .....
GMs rek:
This tech paper will discuss the replacement of the front brake pads and rotors on the C-4 Corvettes. This paper deals specifically with the ‘84 – ‘87 model years, and applies generally to the ’88 through ’96 models. The rear brakes use the same process, so you can use this procedure as a guide for the rear, as well.
General
The disc brake system on the C4 series Corvettes is a well designed, simple to maintain system that uses components that are right off the racetrack. The component parts are designed for very quick service/replacement, and can be easily serviced with very basic hand tools.
The brake pads used on the Corvette are unique to the ‘Vette. They are a high performance, semi-metallic pad. You cannot buy a non-performance, non-metallic pad that will fit a C4. Due to this, the pads are a bit more costly than a semi-metallic pad for your Buick Regal. There are two different part number series for the C4: The 1984 through 1987 cars use the early pad. The 1988 through ’96 cars use a different, much more costly, pad.
Several different manufacturers supply pads for the ‘Vette. Personal preference is a factor in name brand selection, but I have found the Raybestos pads to be well built, well backed (by warranty), readily available, and very well researched and tested by the manufacturer. They offer two grades of pads for the ‘Vette: the “PG” series and the “SS,” or “Super Stop” series.
The “PG” series is a stock, high performance replacement pad. It will meet or exceed the performance of the GM pads. The “SS”series is a step up from this, and provides superior high-temperature braking performance for continuous or heavy braking applications, such as when autocrossing or very sporty driving. It has been my general experience that the pads designed for high temperature, heavy duty applications tend to be less effective under light, cool braking conditions: they come into their peak effectiveness when hot. For this reason, I prefer the standard, “PG” series for use on cars that are used primarily for around-the-town driving and weekend pleasure. Both the “PG” and the “SS” series come with Lifetime Warranties.
In addition to the pads themselves, the rotors may need attention. Excessive heat can warp a rotor, causing a pulsating brake pedal and pulsating braking performance. Pads worn past their limit, exposing the metal backing, can groove and gouge the rotors. It is my personal preference to NOT turn rotors that are not warped or scored: if the rotor is performing smoothly, is not damaged in any way, and only shows light wear, I prefer to simply replace the pads and leave the rotor alone. This extends rotor life significantly. If you need to have the rotor turned due to a pulsating pedal or other rotor damage, make sure you take it to a reputable machine shop that has good, modern equipment: I’ve seen many rotors set up and turned by inexperienced people on poorly maintained equipment that results in a rotor that does not run true, or which has a finish which is not conducive to good braking performance or pad life.
