Brake pads needed

[BenS]

but I didn't expect such a torrent of abuse!

I definitely did not intend to offend with my posts, just pointing out that Czar has probably the most automotive knowledge out of everyone on the forum combined (and we're very lucky to get his technical wisdom).

I also see what you meant RE the pad vs. disc material, misinterpreted that myself.

Don't feel disheartened!

Interesting debate guys! Maybe it`s time to take a brake!! (groan)

I was sensing some friction there!! (getting my coat now) :/

If they are %70 worn, and youve been recommended to change, best do so, although i do take Dave B's point, there is still life left depending on how you use your brakes. (Track day coming up?)
Dont want them getting down to rivets, as its then discs too

Changing pads doesnt appear that hard, and is on my list of DIY jobs to try out. Just a piston wind back tool by the looks

So both Czar (Talking from a high perfomance perspective) and Dave B (From a daily driver perspective) are right

Good. My United Nations bit done here then ;-)

I feel bad for starting a debate now!

Anyhoo, they recommended that the front discs and pads are changed at the same time and wanted £200 for it so i declined.

Im a complete notice with cars so forgive the noob questions but whats the difference between the basic brands on carparts4you and brembo's for example?

I dont mind spending the money if its worth it

Brembo calipers = more pistons, more area = more force applied

Brembo pads = generally bigger + different pad material = improved braking. BUT stickier compound usually means faster wear. Pads only fit in Brembo calipers I would assume, not sure they make pads for everyday calipers.

Do Brembo do discs? Well anyway, high end brake discs may be vented, drilled, slotted or a combination, to improve the cooling mentioned above.

Same principles apply to other brands such as Tarox or Alcon etc.

Dont feel bad, nothing wrong with a heated debate (Notice the pun..) There used to be loads on here... Chiefnerd was spectacular at them, and for most, quite entertaining
Nerdy even took Czar on.

How much of a lip on the disc. Look through the wheel, or take it off, and see how much of a lip on the outer edge. If its quite a lip, should change them

Morning all...(Timberflake)would b interested in wot action u took and how much they cost??

So im absolutely confused now! What would be considered to be the best quality pads and discs to have fitted to my stock dsport plus? I dont want to start changing callipers and stuff

The brake pads function is to through applied hydraulic line pressure apply a slipping frictional force, the applied hydraulic line pressure is such that the caliper and mounting assembly are subject to applied force deflection, when the materials of the caliper and mounting assembly reach their deflective stress limit, the applied deflective force is transferred to the brake pad, the brake pad material when new absorbs the applied hydraulic line pressure and deflective applied force through compressibility of the brake pad material.

The compressibility of the brake pad material reduces as the brake pad material wears, as the brake pad material wears and is subject to countless heat cycles, the materials ability to absorb and dissipate the generated frictional heat reduces, the generated frictional heat from the brake pad is then transferred to the brake disk, brake caliper, mounting assembly and the hydraulic brake fluid.

Thermal resistance between the brake pad and the brake disk prevent the brake disk from absorbing the generated heat at the contact surface of the pad, so the temperature of the brake pad increases and consequently heat soaking of the brake fluid increases and this may cause brake fluid vaporisation leading to a spongy brake pedal feel, reduced brake efficiency commonly known as brake fade.

A 70% wear reduction of brake pad material has a linear thermal reduction proportional to thermal absorption, storage and dissipation of the brake pad and disc assembly, proportional to wear characteristics of both the brake pad and brake disc !!

To be honest, the OEM ones will be best in most circumstances. Citroen designed them to work adequately with the car's performance - if they needed better braking for the weight/speed of the car, they would have bigger brakes as standard.

If you track your car, then upgrading brakes is definitely a strong consideration as they'll get much hotter and fade quicker, see Czar's explanation above.

For street use only, if you wanted to improve stopping power, you could consider EBC greenstuff brake pads. These will wear faster and need replacing more often though, and have an extended, several stage wear-in period compared to the OEM ones.

So if I were going to go to carparts4less which front dics and pads will be as good as the OEM ones? I dont use the car on a track just street use.

Citroen want £245 to replace for the job, but if i can buy equal of better quality myself and get them fitted locally i'll be happy and im sure it'll cost a lot less than £245!

Check Bigfeet's file repository to see if it has part numbers for the brakes assemblies, if not then hopefully someone who knows will see this and respond.

It was Brembo discs and pads I replaced my OEM ones with. Still the original calipers

The biggest improvement you can make to your braking performance, is getting stickier tires.
