A bit tight which is normal but I had to use a hammer and chisel to remove one of these later. firm, but later when I had to take the brake drums off to do the braking work I had to use a hammer and chisel to squeeze between the drum and the spacer and it wasn't easy to tap on. I used the hammer at FULL power for about 20 minutes or so and I'm afraid to reuse the too tight one because it now has structural damage from being stuck and has to be hit with a hammer to remove it - both rims are the same size and one spacer fits both drums but the other pad is too tight/small so I had to take them off and wasting my money. At first I was satisfied but now I am very dissatisfied and will not buy again unless the seller fixes the problem. If I can't use them I wouldn't give them any stars if I could. Seller, please make it right. Many Thanks.
