When I was replacing my brake pads and rotors yesterday, I noticed that I have missing Disc retaining screws from the old rotors, these brakes were previously replaced from a shop a few years ago and I've been driving all this time without it. Question: Are those screws necessary at all or serve any important purposes? I've read somewhere that these screws were used to hold the rotors in place while it was assembled in the factory but not sure if they do anything else afterwards. Without the screws, would they cause brake pulsation over time possibly due to mild back /forth movements, eventually warping the rotors?
Bought a used 2000 mazda 626 with driver's side headlight bulb bursted. Tried to replace without reading any instructions and screwed up. I lost the screw that holds the headlight bulb retaining spring to the housing. I couldn't find any step by step instructions as well. If there is, I apologize and request mods to delete this thread. Hence, this DIY. Sorry no pictures because I was doing it in the parking lot of the hardware store and didn't have camera on me. Edit: I took the pictures of the already assembled headlight unit so the process is more understandable to anyone who is searching this information. Tools: small phillips head screw driver. Bulbs: Your choice, I went with sylvania. Screw: Short 6mm thread metal screw. The screw is a 6mm metal screw, in case anyone is looking for one. I went to mazda dealer and asked them for the screw since I didn't know the specs and didn't want to remove the one from the other side. They said it comes with the whole headlight assembly. WTF? Am I going to buy the whole headlight assembly to replace a screw? F no. Went to hardware store, bought a couple of metal screw of various threads for a dollar and 6mm fit perfectly. However, I would like to mention it is one of the most ridiculous headlight bulb holder design. Not intuitive at all. Took me almost an hour to figure out how to put that spring back on. Tip for the users who get stuck on the headlight bulb replacement like me: Passenger's side is a bit lengthy process since you have to remove the expansion tank. Driver's side is easy. Disconnect the headlight harness by pressing two tabs and pulling the connector out. This is how the back of the headlight will look like once you disconnect the connector. Remove the rubber boot from the housing. You will see a yellow phillips head screw towards the turn signal side. DO NOT remove the screw completely. Notice how the bulb orientation is, the bulb will seat there properly in only one way. Just unscrew it about 2 threads and compress the spring and release it from the opposite side of the screw. Compress the spring and unlatch it from the opposite side of the screw. Swing open the spring like a door hinged at the screw. remove the bulb. Place the new bulb in. The bulb will seat in only one way, the 3 prongs of the bulb face upwards, meaning there won't be any prongs towards the underside of the car. Close the spring like the door. Compress the spring and latch it on the opposite side of the screw. Put the rubber boot back on. Put the connector back on to the bulb. DONE. Now to clean the yellow oxidation: I used turtle wax headlight lens restorer. around $8. No drills, dremels or rotary needed, just your fingers. Comes with paste to clean and spray liquid and sanding pads if the paste doesn't give desired results. Just the paste worked for me on my mazda. However, I tried the spray liquid on my other car fogs. Worked like a charm. The instructions are clear on the packaging and works like a charm. So for people who are using toothpaste and what not to get the headlight shine back, give turtle wax headlight lens restorer a try. Put the paste on a clean cotton cloth. Scrub like crazy on the yellow lens. One lens at a time. Wipe it off. If it doesn't give you a desired result: Go ninja with spray solution and sanding pads according to the instruction. PlastiX has a headlight lens restorer liquid which I use regularly on my other car. So now its going to be plastiX every car wash and if it gets yellow again turtle wax headlight lens restorer is there. Enjoy.
hey, i had to get my alternator replaced and when i got home after it was done, i noticed that the long bolt thats used to put tension on the tension pully was gone. i have no idea how the were able to get the belt tight without that bolt in there but they did. i know to loosen it you first loosen the nut on the pully itself, then you loosen the long vertical bolt to let tension off the belt, obviously the shop didn't know this, because now if i were to loosen the nut on the pully i would have no way to put the tenison back on. this was about 3 months ago, and until now that wasnt a problem, but now i need to replace the crankshaft position sensor and to get it out i have to remove the belt and i cant do it till i have that bolt! how can i replace this bolt?
