base on price from last time i fix my car :

1. 50 per side
2. 80 pair (sparepart)
3. rear shoe = brake drum lor? if u talking bout the cover then thats dunno.
4. 90

*price might be not accurate as long time change already.

**those 3 brake related can go to any tyre shop. just make sure the centre nut not overtighten. the clutch cable, some shop can do.
if engine relate better go to savvy/renault expert shop.

in KL/PJ, i prefer go to Osman Baba shop (DELL CUN AUTO) in pandamaran klang. a lil bit far (use kesas) but worth your trip, as for full check diagnosis. he got the pdt as well. good for if got engine relate problem such as sensor problem.

OR

any big proton service centre. mayb near to your place but pricey.
